根据本发明人等的模拟,在2元件电子控制波导器阵列天线装置的情况下,输入阻抗的变化依赖于元件间隔,在40〜100[D]范围内进行变化,与此相対,在3元件电子控制波导器阵列天线装置的情況下,如图19以及图20所示,被控制在10[Q]以下。 According to the simulation of the present inventors, in the case of the electronic control elements 2 of the waveguide array antenna apparatus, the input impedance variation depends on the spacing element, be varied within 40~100 [D] range, Dui with this, the element 3 a case where the electronic control device of the waveguide array antenna, FIG. 19 and FIG. 20, is controlled to 10 [Q] or less. 3元件的构成中,基本上来说,对应于电·抗值的变化,输入阻抗的变化幅度很小。 3 constituting the element, basically, corresponding to an electrical anti-value changes, changes in the amplitude of the input impedance is small. 另外,3元件电子控制波导器阵列天线装置中,电抗值Xl与x2,被交互切換分配相同值的组合,因此,指向.性图像切換之后的输入阻抗的值相一致。 Further, the electronic control device 3 of the waveguide antenna array means, the reactance values ​​of Xl and x2, are alternately switched same value allocated combination, therefore, point value of the input impedance of an image after the handover coincide. 可以确认,3元件电子控制波导器阵列天线装置与2元件电子控制波导器阵列天线装置相比,匹配设计就容易进行。 Can be confirmed, the electronic control device 3 of the waveguide antenna array means as compared with the electronic control means of the waveguide array antenna element 2, it is easy to match the design.

接下来,対等价权向量法(阵列因数)进行说明。 Next, Dui equivalent weight vector method (array factor) will be described. 一般来说,阵列天线的指向性通过元件単体的指向性与阵列应答向量(阵列因数)之积表示。 Generally, the directivity of the antenna array response vector (array factor) by the directivity of the array element represents the product of radiolabeling body. 为了求出3元件电子控制波导器阵列天线装置的阵列因数,这里使用等价权向量法(参照例如非专利文献2以及4)。 In order to obtain the array factor of the electronic control device 3 of the waveguide antenna array means, as used herein, the equivalent weight vector method (see e.g. Non-Patent Documents 2 and 4).

这是通过转置向量与权向量的内积表示阵列因数,让该权向量与在发送模式下激励该天线时的电流向量等价的方法。 This is the inner product vector by the transpose of the weight vector array representing the factor, so that the weight vector of the current vector when the antenna is equivalent to the excitation method in a transmission mode. 阵列因数D (40如下进行定义。这里,w (w0、wl、w2)为各个天线元件AO、Al、A2的等价权イ直',zs[Q]与'[V]为发送供电系统的输出阻抗与内部电压,xl、x2[Q]分别为与非激励元件Al、A2相連接的可变电抗元件12 — I、12—2的电抗值。 Array factor D (40 is defined as follows. Here, w (w0, wl, w2) of the respective antenna elements AO, equivalent weight Al, A2 of イ straight ', zs [Q] and' [V] to transmit the power supply system output impedance and internal voltages, xl, x2 [Q] and the non-excitation elements are Al, A2 are connected to variable reactance elements 12 - I, the reactance value of 12-2.

另外,定式化在图18的等价偶极模型下进行,因此全部为两倍的系数。 Further, the formula given is carried out at an equivalent dipole model of FIG. 18, all coefficients thus twice.

这里,上述式(18)中的a (¢)、w分别通过下式表示。 Here, in the formula (18) a (¢), w are represented by the following formula.

这里,上述式(20)中的X、U0,分别如下所示。 Here, (20) X in the above formula, U0, respectively, as shown below.

能够通过上述式(18)进行计算的阵列因数D (40中,还考虑到了供电系统与天线的阻抗不匹配所引起的损失。将所加载的可变电抗元件12 Can be calculated by the above formula (18) in an array factor D (40, taking into account also the power supply system and the antenna impedance mismatch loss caused. The loaded variable reactance element 12

图21中显示了元件间隔d=0.15人时的振幅指向性,图22中显示了此时的相位指向性。 Figure 21 shows the amplitude of the directivity when people element spacing d = 0.15, FIG. 22 shows the case of phase directivity. 由于指向性具有対称性,因此在0〜180[度]的范围内进行了图示。 Since said Dui having directivity, and therefore has been illustrated in the range of 0~180 [deg].

另外,下面对3元件电子控制波导器阵列天线装置的电抗分集效果的确认結果进行说明。 Further confirmation result, the following array antenna apparatus of the electric element 3 electronically controlled anti waveguide diversity effect will be described.

如上所述,在3元件电子控制波导器阵列天线装置中,也能够通过进行电抗控制,来变化其振幅相位的方位角依赖性。 As described above, in the waveguide array antenna apparatus 3 an electronic control element, can be electrically controlled by an anti-to change the azimuth angle dependence of amplitude and phase. 通过对其进行适用性使用,能够避免衰减所引起的产生水平下降的条件,也即同振幅反相位状态。 Levels produced by the use of its applicability, it is possible to avoid a decrease in the attenuation due to the conditions, i.e. the same amplitude anti-phase state. 为了对其进行定量确认,进行以下的模拟。 In order to quantitatively confirm them, the following simulation.

该模拟与2元件电子控制波导器阵列天线装置的情況相同,使用等振幅2波模型来进行。 The same as the electronic control elements 2 analog and the waveguide array antenna apparatus, the amplitude of the wave model 2 used for the like. 图23中显示了该模型图。 Figure 23 shows the model of FIG. 具有干扰性的两个波Sl、S2振幅相等,且以随机相位差到达的环境下,将设有3元件电子控制波导器阵列天线装置的情况下所接收的信号设为y。 Having two interfering waves Sl, S2 have the same amplitude and the random phase to reach the environment, the member 3 is provided with a case where the electronic control means of the waveguide array antenna received signal to y. y使用阵列因数D (4>),通过下式表示。 y using an array factor D (4>), represented by the following formula. 另外,两个波的到达方位角4m、¢2在360[度]的范围内不相关,且为随机值。 Further, two waves arrive azimuth 4m, ¢ 2 are not relevant in the range 360 ​​[deg], and a random value. 这里,在两个状态下控制3元件电子控制波导器阵列天线装置的电抗值X!、X2»在选择接收功率(y*y*)变髙的一方的算法下避免衰减。 Here, in the two electronic control state reactance value of the waveguide element X 3 array antenna apparatus!, An X2 »avoid attenuation at selected reception power (y * y *) becomes one of Gao algorithm. X!、X2,使用将相同值的组合互相交替所得到的组合。 X!, X2, using the same combination of values ​​obtained alternately combined with each other.

图24中显示了供电系统阻抗zs==50[D](换算为偶极模型为100[Q]) '元件间隔d=0.15 X的情况下的衰减恶化的累积概率分布(CDF曲线)。 Figure 24 shows the cumulative probability of decay in the case where the power supply system impedance zs == 50 [D] (in terms of a dipole model 100 [Q]) 'element spacing d = 0.15 X deterioration distribution (CDF curve). 将电抗值在0[Q]与50[Q]这两个状态交互控制。 The reactance value at 0 [Q] and 50 [Q] interactive control of these two states. 图24的曲线图的纵轴,为以到达波I的信号功率aoao*为基准的,分集接收信号功率超过了横轴的dB表示值的情况的累积概率(CDF值)。 FIG 24 is a graph of the vertical axis, in order to signal power for the wave aoao * I, as a reference, the diversity reception signal power exceeds the cumulative probability (CDF value) dB represents a case where the value of the horizontal axis. 为了进行比较,在图24中通过虚线表示存在有等振幅的两个到达波的模型中的无指向性的单一天线装置的衰减CDF的理论值(参照下式)。 For comparison, in FIG. 24 indicates the presence of two equal amplitude attenuation of a single non-directional antenna device according to the wave model in the theoretical value of the CDF (see the following formula) by a broken line.

从图24可以得知,3元件电子控制波导器阵列天线装置,与单一天线相比,在CDF值为90%时能够得到了5dB的分集增益301,在CDF值为99°バ时得到约IOdB的分集增益302。 It can be seen from FIG. 24, the electronic control device 3 of the waveguide antenna array means, compared to a single antenna, when the CDF value is 90% is possible to obtain a diversity gain 301 5dB obtain about IOdB CDF value at 99 ° ba 302 diversity gain. 另外,.发生20dB的衰减恶化的概率也降低到约0.5%,30dB约为0.07°バ,与单一天线相比大幅下降。 Further, the probability of occurrence of the deterioration of the attenuation of 20dB is reduced to about 0.5%, 30dB ba about 0.07 °, dropped significantly compared to a single antenna.

图24中,在作为所接收的无线信号的信号功率超过给定的信号功率的情况下的累积概率的CDF值,例如为90%或99%等给定值吋,最好选择并设定让分集増益变为给定值以上,且输入阻抗Ziri不发生实质变化的第I与第2电抗值组。 In FIG 24, CDF value as in the case where the radio signal power of the received signal exceeds a given cumulative probability signal power, for example, 90% or 99% of a given value like inch, is preferably selected and set so zo diversity gain becomes a predetermined value or more, and the input I and a first reactance value set of the second impedance Ziri substantial change does not occur. 另外,在作为所接收的无线信号的信号功率超过给定的信号功率的情况下的累积概率的CDF值,例如为90%或99%等给定值吋,还可以最好选择并设定让分集増益实质上最大的第I与第2电抗值组。 Further, in a case where the CDF value as the signal power of the received radio signal exceeds a given cumulative probability signal power, for example, 90% or 99% of a given value inch like, may also be preferably selected and set so zo diversity gain substantially maximum value of the reactance group 2 I.

接下来,图25中显示了元件间隔与分集增益之间的关系。 Next, FIG. 25 shows the relationship between the spacing element and the diversity gain. 在CDF为90%以及CDF为99%日寸,在元件间隔0.1 A〜0.35 A的范围内,元件间隔与所得到的分集増益之间没有很大的依赖性。 The CDF is 90%, and 99% CDF day inch, in the range of 0.1 A~0.35 A spacer element, there is no great dependence between the spacing element and the enlargement of the diversity gain is obtained. 这意味着,在3元件电子控制波导器阵列天线装置的安装设计中,不需要严格设定公差。 This means that, in the array antenna installation design of the electronic control device the waveguide element 3, need not be strictly set tolerances. 也即,元件间隔可以在0.1 X〜0.35 A的范围内进行设定。 That is, the element spacing can be set in the range A 0.1 X~0.35. · ·

如上所迷,通过该最佳实施方式的相关3元件电子控制波导器阵列天线装置,能够确认通过电抗值切换所得到的天线输入阻抗的变化的抑制。 As fan 3 through the relevant elements of the preferred embodiment of the electronic control of the waveguide array antenna apparatus, to suppress the change can be confirmed by the anti-obtained value switching electrical input impedance of the antenna. 通过在2状态下控制电抗的算法,能够计算出等振幅的2波模型中的分集增益。 In the second state by the control algorithm reactance, and the like can be calculated diversity gain of 2 of the amplitude wave model. 可以得知,相对单一天线,在累积概率分布为90%时能够得到5dB的分集増益,在累积概率分布为99%时能够得到IOdB的分集増益。 It can be known, the antenna is relatively simple, the cumulative probability distribution can be obtained zo diversity gain of 5dB when 90% of the cumulative probability distribution can be obtained IOdB diversity gain zo 99%. 在元件间隔0.1入〜0.35人的范围内所得到的分集増益没有很大的差别,因此,不需要严格的安装公差,在费用方面也很有利。 Element spacing in the range of 0.1 to get into the ~0.35 human zo diversity gain is not much different, and therefore, does not require strict mounting tolerances, is also advantageous in terms of cost.

也即,由于并不強烈依赖于天线元件间隔,因此,在安装天线装置时'不需要严格要求机械公差,在折叠展开式构造或柔软弹性材料所制成天线装置的安装中也很有效。 That is, since the antenna element is not strongly dependent on the distance, and therefore, when mounting the antenna apparatus' not require strict mechanical tolerances required, is also very effective in mounting the antenna device is made of deployable structure or flexible elastomeric material. 该阵列天线的控制装置,硬件构成简単,且通过简单的I位ニ进制控制能够得到很大的衰减改善效果,因此,能够用作可安装在便携式振荡装置或PC卡等民用消费终端装置中的分集天线。 The control device of the array antenna, radiolabeling simple hardware configuration, and ni bits by a simple binary control I can be greatly improved damping effect, and therefore, can be used as the oscillation device mounted in the portable PC card terminal apparatus civilian consumer the diversity antenna.

另外,电子控制波导器阵列天线装置的可变电抗元件,可以通过例如低价的可变电容ニ极管构成,因此,具有I个激励元件与两个非激励元件的电子控制波导器阵列天线装置,与基于单极双掷RF开关的以前的2元件选择式分集天线相比,成本较低。 Further, the electronic control device the waveguide antenna array variable reactance element, for example, by low-cost variable capacitance diodes constitute ni, therefore, I have two electronic excitation and non-excitation elements of the control device the waveguide array antenna It means, based on comparison with the previous 2 selective diversity antenna elements single pole double throw RF switch and low cost. 另外,可变电容ニ极管通常在逆偏置电压下工作,因此,没有像PINニ极管开关那样的导通时的直流电流消耗。 Further, Ni variable capacitance diodes typically operate at a reverse bias voltage, and therefore, the writing is not as PIN diode switch when the DC current consumption as conduction. 与FET开关相比,可变电容ニ极管也较为低成本且低损耗。 Compared with the FET switch, the variable capacitance diode ni is relatively low cost and low loss. 另外,电子控制波导器阵列天线装置,即使天线元件间隔比较窄,也能够工作,因此,熊够让天线装置全体小型化。 Further, the electronic control of the waveguide array antenna apparatus, even when the antenna element spacing is relatively narrow, it is possible to work, therefore, enough to bear the entire apparatus so that the size of the antenna.

上述的最佳实施方式中,对3元件电子控制波导器阵列天线装置进行了说明,但本发明并不仅限于此,还可以是具有I个激励元件与偶数个非激励元件的电子控制波导器阵列天线装置。 The above-described preferred embodiment, the electronic control apparatus for an array antenna waveguide element 3 has been described, but the present invention is not limited thereto, but may be I having an even number of excitation elements and the electronic control non-excited waveguide array elements The antenna device. 也即,该电子控制波导器阵列天线装置,具有用来接收被发送的无线信号的激励元件,与距离上述激励.元件给定间隔而设置的偶数个非激励元件,以及分別与上述各个非激励元件相连接的偶数个可变电抗元件,通过变化上述各个可变电抗元件所设定的电抗值,将上述各个非激励元件用作波导器或反射器,变化作为该电子控制波导器阵列天线装置的阵列天线的指向特性。 That is, the electronic control of the waveguide array antenna apparatus, an excitation element for receiving the radio signal is transmitted, the distance from the excitation.

从3元件的阵列天线的控制装置100A的供电连接点AO■出的所接收的无线信号,被前置放大器402放大之后,输入到频谱分析仪403中。 From the control point device 100A power supply connector element array antenna 3 AO ■ received wireless signal out, after amplified by a preamplifier 402, an input to the spectrum analyzer 403. 频谱分析仪403在零档模式下进行工作,取出与所接收的无线信号的功率強度成正比的电压输出,经与个人计算机401相连接的A/D变换端ロ,将其保存到个人计算机401内的硬盘存储器中。 Spectrum analyzer 403 in the zero span mode operation, the power is proportional to remove the wireless signal strength of the received voltage output by A ro to the personal computer 401 is connected to A / D conversion ends, save it to the personal computer 401 hard disk storage medium. 电抗值的切換,通过与个人计算机401相连接的D/A变换模式,与A/D变换同步,在VH、Vl之间切换可变电容ニ极管61、62的逆偏置电压来进行。 Switching reactance value D by a personal computer connected to 401 / A conversion mode, synchronous with the A / D conversion, switching the variable capacitance diode reverse-bias voltage Ni to be between 61 and 62 VH, Vl. 该实施例中,由于D/A变化模式的输'出电压最大为10[V],因此,通过直流放大器404放大到2.5倍,与3元件阵列天线装置100A上的可变电容ニ极管61、62相连接。 In this embodiment, since the input D / A change pattern 'of a maximum voltage of 10 [V], and therefore, the DC amplifier 404 to 2.5 times, and the variable capacitance element array antenna apparatus 100A 3 ni diode 61 , 62 are connected. 切换周期为1.5微秒,相对图38的测定系統的移动速度,让电抗值的切換前后的测定结果看起来像几乎是同时所测定的值。 Switching period is 1.5 sec, the measurement system 38 of FIG relative moving speed, so that the measurement result before and after switching reactance looks like almost simultaneously measured values. 该值是参考通过空间分集天线与RF开关所进行的随机区域测定法的研究结果而決定的(参照例如非专利文献5以及6)。 The reference value is the result of research by the random spatial region and a diversity antenna assay performed by RF switch is determined (see e.g. Non-Patent Documents 5 and 6). 图39为说明图35的阵列天线装置100A的实验环境的布局的平面图。 FIG 39 is a plan view illustrating the layout of the experimental environment of the array antenna 35 of the device 100A of FIG. 如图39所示,在将5.2GHz的无线发送器410置于房间415的中心处的状态下,图38的接收器侧的测定系統,沿着虚线411以一定的速度移动进行測定。 As shown in FIG. 39, in the 5.2GHz wireless transmitter 410 is placed at the center of the room 415, and Fig measurement system the receiver side 38, measured along the dotted line 411 at a constant speed movement. 阵列天线装置100A的设置高度在发送侧与接收侧都为1.2m。 Array antenna apparatus 100A is disposed at the height of the transmission side and the receiving side are 1.2m.

图40为作为图35的阵列天线装置100A的实验结果,显示分集増益的对应于标准化功率的CDF值的曲线图。 FIG 40 is a result of the array antenna as an experimental device 100A of FIG. 35, showing the diversity gain corresponds to the enlargement of the graph of the normalized power CDF value. 该实验結果,显示了根据图39的实验环境中的测定结果所导出的标准化了的接收功率[dB]的CDF值的曲线。 The experimental results show curves derived from the measurement results of the experimental environment of FIG. 39 is a normalized received power [dB] to CDF value. 这里,级轴的CDF值为3元件阵列天线装置100A中的接收功率,显示了在比横轴的值大的情況下所导出的累积概率。 Here, CDF value of the received power element array antenna apparatus 100A 3-stage shaft, showing the cumulative probability value at the horizontal axis is larger than the case where derived. 状态I、状态2分别为输入给加载在非激励元件A1、A2中的各个可变电容ニ极管61、62的逆偏置电压为(VI,V2) = (0,25) [V]、(VI, V2) = (25,0) [V]的情况下的累积概率分布曲线。 State I, state 2 are input to the non-load excitation elements A1, A2 of each of the variable capacitance diode reverse-bias voltage ni 61 and 62 is (VI, V2) = (0,25) [V], the cumulative probability (VI, V2) = (25,0) [V] of the case profile. 选择逆偏置电压的切換前后中的接收功率较髙的一方,所选择合成的结果的累积概率分布曲线,通过实线(分集)来表示。 Selecting reverse-bias voltage received power before and after switching of one of more Gao, the synthesized result of the selection cumulative probability distribution curve, represented by the solid line (diversity).

.状态I以及状态2的情况下的結果,几乎沿着图40中的瑞利曲线,预想图39的实验环境为直接波的影响较小的衰减环境。 The results in the case of a state 2 and state I, almost along the Rayleigh curve in FIG. 40, FIG expected experimental environment 39 is less influence of a direct wave fading environment. 通过不进行分集的情况下与进行的情況下的接收功率的差,也即分集増益,来评价3元件阵列天线装置100A的分集能力。 By without performing diversity reception power difference for the case where, zo diversity gain i.e., the ability to evaluate the diversity antenna 3 element array device 100A. 从图40可以得知,在累积概率分布(CDF值)为90%的情况下进行比较,通过分集接收得到了约4dB的分集増益;303,可以看出接收功率得到了改善。 It can be seen from FIG. 40, the cumulative probability distribution (CDF value) of 90% were compared, obtained by the diversity reception diversity gain about 4dB of zo; 303, can be seen that the received power is improved. 另外,在衰减更深的CDF值为90%吋,得到了约7dB的分集增益304。 Further, the deeper in the attenuation value of 90% CDF inch obtain diversity gain of 7dB about 304.

'如上所述,提案了基于3元件阵列天线装置100A的电抗分集,并通过实验进行了确认。 'As described above, the proposals based on the electric element array antenna apparatus 100A 3 anti-diversity, and confirmed by experiments. 通过试制作,证明了平面型3元件阵列天线装置IOOA能够通过电介质基板20a与两个可变电容ニ极管61、62构建。 Produced by the test proved 3 elements planar array antenna apparatus IOOA can be Ni electrode tubes 61 and 62 through the dielectric substrate 20a and the two variable capacitance construct. 这意味着平面型3元件阵列天线装置100A能够通过低价安装。 This means that the planar array antenna elements 3 can be mounted by means 100A Low. 另外,如上所述,3元件阵列天线装置100A中,通过实验确认了切換前后的天线装置的输入阻抗是一定的。 As described above, the antenna 3 element array device 100A, the input impedance of the experimentally confirmed that the antenna device is constant before and after switching. 测定分集増益的结果得知,在CDF值为99%时得到了约7dB的分集増益。 Zo measurement diversity benefits that result to obtain diversity gain enlargement of about 7dB when the CDF value is 99%. 另外,根据实验能够确认,通过平面型3元件阵列天线装置100A所进行的分集接收,显示出了耐多路衰减能力。 Further, it can be confirmed according to the experiment, performed by the diversity of the planar array antenna element 3 receiving apparatus 100A, showing the multidrug-resistant way damping capacity.

第6最佳实施方式.图41为说明本发明的相关第6最佳实施方式的阵列天线装置100B的平面图。 A sixth preferred embodiment. FIG. 41 is a diagram of an array antenna 6 Related best mode embodiment of the present invention, a plan view of the apparatus 100B. 该第6最佳实施方式的相关阵列天线装置100B,与图9的阵列天线装置相比,以下几点不同。 Related array antenna of the sixth preferred embodiment of the apparatus 100B, as compared to the array antenna apparatus of FIG. 9, the following differences. (I)具有图41中所示基板数据的电介质基板20b,代替电介质基板20。 A dielectric substrate (I) having a data substrate 41 shown in FIG. 20b, in place of the dielectric substrate 20. (2)接地导体Ila的上下方向的长度为Ag。 Length in the vertical direction (2) Ila ground conductor is Ag. 这里,为通过电介质基板20b的介电率sr所求出的有效波长。 Here, for the effective wavelength by dielectric substrate 20b of the dielectric constant sr is obtained.

另外,图41中,t为电介质基板20b的厚度,er为其介电率,O为形成在电介质基板20b上的导体的导电率。 Further, in FIG. 41, t is the thickness of the dielectric substrate 20b, its dielectric constant ER, O is the conductivity of the conductor formed on the dielectric substrate 20b.

用于该最佳实施方式中所使用的阵列天线装置100B的控制装置,与图 The control device array antenna apparatus in the preferred embodiment are used for the embodiment 100B of FIG.

I的构成相同。 I the same configuration. 这里,非激励元件Al、A2分别加载了作为可变电抗元件12—1、12—2的可变电容ニ极管。 Here, the non-excitation elements Al, A2, respectively, is loaded as a reactance element 12-1 ni variable capacitance diode. 加载电抗只在可变电容ニ极管只能够得到.负电抗,因此,在让介电性处于可变范围内的情况下,根据需要串联或并联连接阻抗。 Only Ni loading reactance diode can be obtained only in the variable capacitance. Negative reactance, therefore, let dielectric is within a variable range, the impedance is connected in series or parallel as desired. 加载给可变电容ニ极管的直流偏压,通过图I的控制器10迸行切换。 Loading a DC bias of the variable capacitance diode ni, switched by the controller 10 into line I in FIG. 也即,将加载电抗值(X1, X2)在(X1, xh)以及(xh,X1)这两个值之间切換,变化该阵列天线装置100B的指向性。 That is, the loading reactance value (X1, X2) between (X1, xh) and (xh, X1) to switch the two values, the change in the directivity of the array antenna apparatus 100B. 该最佳实施方式值,将决定各分集支的指向性的加载电抗值,称作“分支电抗”。 The value of the preferred embodiment, determines the directivity of the sub loading reactance value set branch, called "branch reactance." 因此,通过上述电抗值的常数xh,X1所決定的两个指向性为“分集支”。 Thus, the constant of the reactance XH, two X1 directivity determined as "diversity branches." 根据该最佳实施方式的相关构成,能够不通过切换来变化天线的阻杭,二通过固定常数电路进行匹配。 The relevant components of the preferred embodiment, antenna can not be varied by the switching barrier Hang, two fixed constant by matching circuits. 该最佳实施方式中,电抗值的切換,通过单ー接收电路切换天线,可以使用天线切换分集(参照例如非专利文献7)或天线选择分集(参照例如非专利文献8以及9)的算法。 The preferred embodiment, the reactance value of the handover, handover antenna through a single ー reception circuit may use an antenna switching diversity (see e.g. Non-Patent Document 7) or antenna selection diversity (see e.g. Non-Patent Documents 8 and 9) of the algorithms. 以下通过后者的算法进行控制。 The latter is controlled by the following algorithm. 一般来说,如果在无线接收器的天线系统中切換分集支,接收无线信号的相位就会变得不连续,至少在I〜2个信号间会出错。 In general, if the switching diversity branches in a radio system receiver antenna, the received radio signal becomes discontinuous phase, at least an error between I~2 signals. 为了避免这种状況,在接收帧或时隙的开头部三设置的前同步码区间中,将“分支电抗”在X1, Xh这两个值之内切換,在RSSI ( Receive Signal Strength Indication,称作所接收电波信号的強度的数值化值)高侧固定分支电抗,接收该时隙的数据区间。 To avoid this situation, in the preamble interval received frames or slots provided in the open head of three, the "branch reactance" in X1, Xh handover within these two values, the RSSI (Receive Signal Strength Indication, called for the numerical value of the received radio signal strength) is high-side fixed reactance branch, the reception data of the time slot interval. 因此,如果衰减相対时隙长度足够延迟,就能够得到与检波后选择合成的分集同等的特性。 Therefore, if the slot length sufficient Dui attenuated phase delay, can be obtained with the same characteristics of post-detection selection diversity synthesis.

接下来,对使用该理想实施方式的相关阵列天线装置1.00B等的计算机模拟及其结果进行说明。 Next, computer simulation using this embodiment over the embodiment associated array antenna apparatus and the like 1.00B results will be described. 另外,该计算机模拟中,通过计算机模拟来评价多路传送环境下的电抗分集接收的误码率特性。 Moreover, the computer simulations, to evaluate the electrical multiplex transmission environment by computer simulation reactance component diversity reception error rate characteristic. 该计算机模拟中的各元素如表I所示。 Each element of the computer simulation are shown in Table I below.

该计算机模拟中使用以下两个天线模型。 Using two antennas in this computer simulation models.

(1)设置在无限地板上的具有半径为1/100波长的圆柱形状的单极天线装置(以下称作无限地板模型)。 The monopole antenna apparatus (1) is provided on the floor having an infinite radius of a cylindrical shape 1/100 wavelength (hereinafter referred to as infinite floor model).

(2)在图41中所示厚度1:=0.6111111的高频用双面印刷基板(以下称作印刷基板)所制成的电介质基板20b上所形成的作为3元件电子控制波导器阵列天线装置的阵列天线装置100B (以下称作印刷基板模型)。 (2) 41 in thickness as shown in FIG. 1: = 0.6111111 high-frequency double-sided printed board (hereinafter, referred to as a printed circuit board) as an electronic control device 3 of the waveguide antenna array means 20b on a dielectric substrate made of formed the array antenna apparatus 100B (hereinafter referred to as a printed board model). 这里,在电介质基板20b上形成条形导体所构成的微波传送带线路,其前端从接地导体Ila的最上边向上延伸人/4 (这里,人为自由空间波长)。 Here, the strip conductors forming the microstrip line formed on a dielectric substrate 20b, which extends from the front end of the uppermost ground conductor upwardly al Ila / 4 (here, artificial free space wavelength). 测定频率为5.2GHz。 Measuring frequency of 5.2GHz. 微波传送带线路的线路宽度为让条形导体的特性阻抗为50[ Q ]的值。 The line width of the microstrip line so that the characteristic impedance of strip conductors 50 [Q] value. 因此,假定各个元件A0、Al、A2下端的端ロPO、PK P2,与构成单极元件的各个元件A0、Al、A2的接地导体Ila的最上边中的电流几乎相等。 Therefore, assuming that the individual elements A0, Al, A2 of the lower end of the ro PO, PK P2, the respective elements constituting the monopole element A0, Al, A2 uppermost current Ila ground conductor in nearly equal.

该计算机模拟中,在基站中进行电抗分集接收,假定传送线路为图42所示的杰克(Jakes)模型。 The computer simulation, a reactance diversity reception in the base station, Jack (Jakes) model assumes that the transmission line 42 shown in FIG. 也即,M个单波随机从方位角(DOA) 到达。 Also ie, M random arrival wave from single azimuth (DOA). 各个单波的DOA均匀分布在0—2 中,各个单波的相位与振幅分別为均勻分布以及瑞利分布。 DOA individual single wave in evenly distributed 0-2, each single phase and amplitude waves are Rayleigh distribution and uniform distribution. 这里,hm、4) m分别为第m个单波的传递函数以及DOA。 Here, hm, 4) m are the m-th transfer function of the single wave and DOA. 单波的传递函数,是与激励元件AO的位置相对应的。 The transfer function of the single wave excitation with the position corresponding to the AO element. 如果给出各个单波的I相位与振幅,到接收电路的输入为止的传递函数,就成为电子控制波导器阵列天线装置的指向性、分支电抗的函数,一般来说,在N+1元件的情况下,通过下式来表示。 If I is given of each single phase and amplitude of the wave, up to the input of the receiving circuit of the transfer function, it is a function of the electronic control directivity of the waveguide array antenna apparatus, branched reactance, in general, the N + 1 elements case, is represented by the following formula.

也即,选择传递函数(Xp Xh)与(Xh,X1)的绝对值中较大的一方,作为接收信号的振幅。 That is, to select the transfer function (Xp Xh) and (Xh, X1) of the absolute value of the larger one, as the amplitude of the received signal. 假定加法性白高斯噪声(AWGN),为接收器输入中的热噪声,如果其功率密度为NQ,则能够求出对应于衰减变动的瞬时信号与噪声功率比(Ei/No)。 Assumed that the additive white Gaussian noise (the AWGN), thermal noise in the receiver input, if the power density of NQ, it is possible to determine the instantaneous fading variation corresponding signal to noise power ratio (Ei / No). 这里,设调制方式为BPSK,假定通过延迟检波进行解调,则误码率(以下称作BER) Pc通过下式来表示(參照例如非专利文献10)。 Here, the modulation scheme is set BPSK, assuming demodulated by differential detection, the bit error rate (hereinafter referred to as BER) Pc expressed (see e.g. Non-Patent Document 10) by the following formula.

这里 Here

'该计算机模拟中,每个接收时隙(帧)中,通过随机数产生各个单波的hm、求出传递函数h (X1)与传递函数]! (xh),或传递函数h (X1.xh)与传递函数X (xh、X1),通过上述式(28)求出各个接收时隙的BER。 'This computer simulation, each receiver slot (frame), a random number is generated by each single wave hm, to obtain the transfer function h (X1) and the transfer function]! (XH), or transfer function h (X1. XH) with a transfer function X (xh, X1), to obtain a BER of each received time slot by the above formula (28). 也即,让时隙中没有衰减变动,对时隙长度假定足够迟的衰减。 That is, let the time slot change without attenuation, assuming that the length of the time slot late enough attenuation. 接下来,対等价权向量的计算进行说明。 Next, calculate the equivalent weight vectors Dui be described. 首先,通过上述式(19)以及式(20)计算出等价权向量W。 First, an equivalent weight vector calculated by (19) and (20) above formula W. 导纳矩阵Y的各个要素,使用根据表I所示的元件形状与配置,通过矩(moment)法所求出的下列值。 The elements of the admittance matrix Y, using the shape of the element configuration shown in Table I, the moment (Moment) the following values ​​determined law.

(1)无限地板模型的情況下的导纳矩阵的各要素 Admittance matrix of each element in the case of (1) an unlimited floor model

(2)印刷模型的情况下的导纳矩阵的各要素 Admittance matrix of each element in the case (2) Printing Model

这里,单位为S (西门子,Q-1),表示导纳矩阵Y的m+1行n+1列的要素。 Here, the unit of S (Siemens, Q-1), represents the row n + m + 1 elements of an admittance matrix Y. 关于以上所得到的等价权向量W,在变化电抗值X1或电抗值X2时的轨迹,在使用无限地板模型的情况下,如图43至45所示,在使用印刷基板模型的情况下,如图46至48所示。 Obtained above on an equivalent weight vector W, the track change reactance X2 when X1 or reactance values, in the case where the infinite floor model, as shown in FIG. 43 to 45, in a case where the printed circuit board model, 46 to 48 as shown in FIG. 在前者的无限地板模型的情况下,下式成立。 In the case of unlimited floor of the former model, the following equation holds.

(w0 W1 ) =wT (32) (W0 W1) = wT (32)

另外,在后者的印刷基板模型的情況下,下式成立。 Further, in a case where the printed circuit board of the latter model, the following equation holds.

(W0 W1 W2 ) =Wt 1-33) (W0 W1 W2) = Wt 1-33)

根据非专利文献11,从电抗值X1或电抗值X2到等价权Wo、W1或W2的映射是一次变换,因此,它们的轨迹都是圆,在减小电抗值X1或&时的旋转方向都是逆时针方向。 According to Non-Patent Document 11, X2 equivalent weight Wo from the reactance value of the reactance value X1, W2 or W1 of a mapping transformation is, therefore, their trajectories are circular, the direction of rotation in reducing the reactance value of X1 or & It is counterclockwise. 另外,图43至图45中,从0到一80Q每10Q绘制I个电抗值X2。 Further, in FIG. 43 to FIG. 45, plotted from 0-1 80Q I reactance value X2 each 10Q.

接下来,对BER特性进行说明。 Next, the BER characteristics will be described. 使用所得到的等价权W,通过上述条件进行计算机模拟。 The use of equivalent weight W obtained by the computer simulation above-described conditions. 所得到的BER特性如图49所示。 The resulting BER characteristics shown in Figure 49. 为了进行比较,还显示了通过设置得足够远(10A )且匹配的十分理想的无限地板模型(单极天线)所进行的空间分集,与该单极天线的无分集特性。 For comparison, also shown very good spatial diversity by providing unlimited floor model far enough (10A) and the matching (monopole) carried out, the characteristics of the non-diversity monopole antenna. 分支电抗(xh、 Branch reactance (xh,

X丨),对于无限地板模型,显ボ了(O,—30) [Q]与(0,~60) [Q]的情况,对于印刷基板模型,显示了(0,—70) [Q]与(0,-110) [Q]的情况。 Shu X), for unlimited floor model, a significant Baldwin (O, -30) [Q] where the (0, ~ 60) [Q], the model for the printed circuit board, shows (0, -70) [Q] and (0, -110) [Q] case. 其等价权在图43中通过箭头表示。 Equivalent weight which is indicated by arrows 43 in FIG. 无限地板模型中,在(0,一60) [Q]的情况下特性最好,能够得到与空间分集几乎一致的特性。 Unlimited floor model, in the case of (0, a 60) [Q] characteristic best, possible to obtain space diversity characteristics nearly identical. 另外,在印刷基板模型中,(0,一110) [Q]的情況下特性良好,但对于空间分集来说,在BER= ICT3中能够看到约3 dB的恶化。 Further, in the printed circuit board model, the case where (0, a 110) [Q] good characteristics, but for spatial diversity, in a BER = ICT3 can be seen in the deterioration of approximately 3 dB.

根据以上結果,为了得到高分集増益,考虑在分集支之间,将等价权在复平面上间隔开设置。 From the above results, in order to obtain a high diversity gain zo, considering the diversity branches between the equivalent weight in the complex plane disposed spaced apart. 因此,在电抗分集的设计中,可以设定分支电抗,让对应的等价权在复平面上互相离开。 Therefore, in designing the reactance diversity, the reactance can be set to branch, so that the corresponding equivalent weight away from each other in the complex plane. 根据图43至图45可以得知,分支电抗(0,一60)、(一60,0) [Q]的组合延续上述基准。 Can be known in accordance with FIGS. 43 to 45, the reactance branches (0, 60 a), (a 60,0) [Q] a continuation of the reference composition. 另外,在印刷基板模型中也能够看到约3dB的恶化。 Further, in the printed circuit board can also see the model of the deterioration of about 3dB. 但是,恶化要因之ー是阻抗不匹配所引.起的,通过简单的匹配电路能够容易的改善。 However, for a consequent deterioration ー impedance mismatch is cited. Played by simply matching circuit can be easily improved. 激励元件AO的等价权w0,是通过电抗匹配时的电流来标准化该元件AO的电流,因此,越远离Wo= I+j0, VSWR就越增加,增益下降下式程度的[dB]。 AO excitation element equivalent weight w0 is the current through the reactance element of the matching AO normalized current, and therefore, the farther from Wo = I + j0, the more increases the VSWR, gain reduction degree of the formula [dB].

图46的(xl,x2) = (0,-HO) [Q],对(w0=0.97_j0.53)的增益降低,根据上述式(34)为1.5dB,因此,对设置有适当的阻抗匹配电路的情况下的空间分集恶化为剩余的1.5dB,在BER=10_3中为10.5dB的分集増益。 FIG 46 (xl, x2) = (0, -HO) [Q], gain (w0 = 0.97_j0.53) is lowered, the appropriate impedance of the formula (34) is 1.5dB, therefore, there is provided in accordance with space diversity in the case where the deterioration of the matching circuit for the remaining 1.5dB, as in the BER = 10_3 zo diversity gain of 10.5dB.

■但是,图49的BER特性的曲线,与空间分集几乎平行,这表示作为分集支的相关几乎变为O。 ■ However, the curve, the BER characteristic spatial diversity FIG 49 is almost parallel, which means that as the correlation becomes substantially diversity branches O. 因此,剰余的1.5dB的恶化,表示平均増益(功率増益在全方位下的平均值)对理想的单极天线约为0.7。 Therefore, the deterioration for Surplus than 1.5dB, and zo represents the average gain (gain in full-zo power under the average) for the ideal monopole antenna is about 0.7. 我们认为这是除了印刷基板模型的电介质基板20b的电介质损耗tan 8以及导电率所引起的损耗之外,解析模型的不完全性所引起的。 We believe this is in addition to the loss of the dielectric substrate 20b of the printed circuit board model dielectric loss tan 8, and conductivity caused by incomplete due to the analytical model. 也即,以上的解析,是根据图41的各端ロPO、PK P2中的电流,与单极天线的元件供电部(接地导体I Ia的最上边)相等的假定(近似)所进行的,但实际上由于3根条形线路相互之间的影响,一般是不同的。 That is, the above analysis, ro is the current PO, PK P2 in accordance with the respective ends 41, equal to the monopole antenna element power supply portion (ground conductor of the uppermost I Ia) assume (approximate) carried out, but in fact due to the strip line 3 between each other, it is generally different.

根据以上,作为电抗分集的设计基准,可以进行以下总结。 According to the above, as a design reference reactance diversity, it can be summarized as follows.

(1)分集支(所切換的两个指向性)之间,让等价权在复平面上互相间隔开。 (1) between the diversity branches (two directivity of the switched), mutually spaced apart so equivalent weights in the complex plane. 也即,进行设定让复平面上的分集支之间的距离最大。 That is, set so that the distance between the diversity branches in the complex plane maximum.

(2)如果激励元件AO的等价权接近I+jO,则可以省略天线装置与供电电缆之间的阻抗匹配电路。 (2) If the excitation element equivalent weight proximity AO I + jO, an impedance matching circuit may be omitted between the antenna device and the power supply cable.

上述(I)是根据特定条件下的模拟所得到的,对于其普遍性尚需在理论上进行探讨。 (I) above is a simulation obtained under certain conditions, yet to be explored in theory for its universality. 但是,在分集支之间的等价权很接近的情况下,可以得知,两者的指向性也很接近,枝间的接收电平变高,分集増益降低。 However, in the case where the sub-set of branched equivalent weight between very close, can be known, the directivity of both are very close, the reception level becomes high between the branches, the diversity gain zo reduced. 因此/上述(I)至少是必要条件。 Thus / (I) above at least a necessary condition.

附录 appendix

.下面,使用非专利文献11中的理论,对加载电抗,也即分支电抗与等价权之间的关系进行理论说明。 Next, using the theory of non-patent document 11, for loading reactance, i.e. the relationship between the reactance branches Equivalent Weight theoretical explanation. 首先,使用行列式法则(cramer法则)的今式,求解出关于等价权向量w的上述式(20),得到下式。 First, rule determinant (Cramer rule) in this formula, solved equivalent weight vector w on the formula (20), to give the following equation.

这里, Here,

V = Y- I +X= (v0 V ! V2 Vn ) ; 0 S k gN (36) V = Y- I + X = (! V0 V V2 Vn); 0 S k gN (36)

接下来,首先对等角性进行说明。 Next, first equiangularity explained. 对某个k,在将i芒k (O^i^N)时的所有电抗Xi固定起来时的电抗Xk到等价权向量Wk以及Wi的映射为一次变换,是等角映射。 A pair of k, when the electric power when all of Mount i k (O ^ i ^ N) up against a fixed anti-Xi to Xk equivalent weight vector Wi and Wk is mapped to the primary conversion, is an isometric mappings. 证明如下。 Certify as follows.

某个矩阵V中,包含有电抗Xk的要素只有対角要素的第k+1行k+1列。 A matrix V, comprising reactance elements Xk only the k + 1 th row of diagonal elements Dui k + 1. 将作为上述式(18)的分母的det (V)在第k+1 (O^k^N)列中展开,得到下式。 The denominator det expand as the above formula (18) (V) of the first k + 1 (O ^ k ^ N) column, to give the following equation.

这里,Vmn为从矩阵V中去掉m行n列所得到的矩阵,Zmn表示导纳矩阵Y—I的第m行n列要素。 Here, Vmn is the matrix of m rows and n columns to remove obtained from the matrix V, Zmn denotes the m-th row admittance matrix Y-I n columns of elements. 因此,包含有Xk的项只是右边第I项,关于电抗xk是I次式。 Therefore, Xk contains just the right item to item I, on reactance xk are times I type. 同样,关于各个Xi也是I次式。 Similarly, with respect to each Xi is also the time I type. 另外,上述式(18)的分子也一样,如果在第k+1列中展开,则能够得到下式,不包括xk。 Further, the molecule of the formula (18), too, if deployed in the k + 1, the following equation can be obtained, excluding xk.

另外,关于各个Xi是I次式。 In addition, for each Xi is the time I type. 也即,变为下式的形式。 That is, the formula becomes the following form.

因此,等价权%是来自电抗Xk的(关于复函数)一次变换,也是来0电抗Xi的一次变换。 Thus, the equivalent weight percent (on a complex function) from the primary conversion of the reactance Xk, 0 to reactance Xi is the primary conversion. 所以,根据一次变换的性质,变换某个特定的电抗时的等价权Wk的轨迹为圆。 Therefore, depending on the nature of the primary conversion converts a particular equivalent weight Wk track during circular electromigration resistance. 特别是,在固定电抗Xi (0彡k<N—1,i^k)并变换电抗Xk吋,等价权Wk描绘出通过原点的圆轨迹。 In particular, the fixed reactance Xi (0 San k <N-1, i ^ k) and converting reactance Xk inch, equivalent weight Wk circular locus drawn through the origin.

接下来,下面对等价权轨迹的旋转角的共同性进行说明。 Next, an angle of rotation of the common equivalent weight trajectory is described. 如上所述,上述式(35)的分母为电抗Xi的一次式,对所有的k都是共同的。 As described above, the above-described formula (35) in the denominator of a formula of the reactance Xi, k are all common. 另外,分子在i#k时,在电抗Xi的一次式中i=k的情况下,不包括电抗Xi。 Further, when molecules i # k, anti Xi is a formula in the electrical case of i = k, excluding reactance Xi. 因此,等价权Wk能够写成下式的形式。 Thus, the equivalent weight Wk formula can be written in the form.

这里,aik、bik、0是通过导纳矩阵的逆矩阵Y'信号源阻抗を以及加载电抗Xi (i^l)所决定的复数,不包括ろ。 Here, aik, bik, 0 is the inverse matrix by the admittance matrix Y 'of the signal source impedance and a plurality of load wo reactance Xi (i ^ l) is determined, excluding ro. 特别是,在k=I的情況下,aik=Oo此时,上述40的右边第2项的分母jXi+Ci对应于电抗的变换,让复平面上的直线运动,因此,根据一次变换的性质的等价权Wi的轨迹为通过原点的圆。 In particular, in the case k = I case, aik = Oo At this time, the right side of the above-described 40 denominator jXi second term + Ci corresponding to the conversion reactor, so that the linear motion in the complex plane, and therefore, according to the nature of the primary conversion of Wi right track equivalent of a circle through the origin. 这里,jXi + C^所有的k是共同的,因此,等价权Wk通过复数bik对I/ Cjxi+Ci)的轨迹进行相似变换与旋转,通过复数aik进行平行移动。 Here, jXi + C ^ k is common to all, and therefore, the equivalent weight Wk similarity transform with a rotation trajectory of I / Cjxi + Ci) by complex BIK, moved in parallel by a plurality aik. 因此,轨迹圆上的旋转角,对所有的等价权Wk包含有I/ Cjxi+ q)的圆轨迹上的旋转角与旋转方向,是共同的。 Thus, the rotation angle of the trajectory circles of all equivalents weights Wk comprising rotation angle of the rotational direction of the circular track has I / Cjxi + q) is common. 也即,如果由于电抗Xi的适当变化,让等价权^在轨迹圆上旋转角度0,则等价权Wk也在同一个方向上旋转角度e。 That is, since if the reactance Xi is appropriately changed, so that the equivalent circle on the right track ^ 0 rotation angle, the rotation angle equivalent weight Wk e are the same one direction.
