An antenna device for synthesizing the output by using two or more types of aerials and receivers when receiving signal propagation. It provides two orthogonal linear polarizations in one antenna, which significantly reduces the installation area, installation cost, and maintenance cost. .

Such a conventional dual polarized antenna device is a type that is most commonly designed in the form shown in the drawings for explaining the element arrangement and radiation pattern of the conventional dual polarized antenna of Figure 1 is the most widely used.

The conventional dual polarization antenna device as shown in FIG. 1 (a) has a first polarization element portion 1 and + 45 ° formed of elements arranged in the vertical direction on the reflector plate 5 at an angle of -45 ° with respect to the vertical axis. And a second polarization element portion 4 composed of elements arranged in an inclined vertical direction, wherein the element of the first polarization element portion 1 is connected to the first polarization input / output portion through the first polarization output divider 2. 3), the element of the second polarization element portion 4 is coupled to the second polarization input / output portion 6 through the second polarization output divider 5.

As described above, dual polarization can be generated in one antenna device, so that the polarization diversity effect and the air line facility are simplified in the communication system as described above. However, as the antenna device is installed vertically, the link antenna or the mobile terminal of the repeater There is a problem that the transmission / reception gain is reduced by about half because any one polarization is polarized by 45 ° with respect to a vertical polarization that is mainly used.

At this time, about half of the other signals lost can be compensated by being received in different polarization strings, but the cost and size of the device are increased because dual output units are required to separate transmissions.

In conclusion, the conventional dual polarization antenna apparatus has the effect of simplifying the polarization diversity effect and the air line facility, but the gain is reduced during the downlink, the handover is unstable when the coverage overlap of the wireless communication system, and the data There is a fatal problem as an antenna device due to quality degradation such as transmission delay and interference with the surroundings.

Accordingly, the present invention was devised to improve the problems of the conventional dual polarized antenna device as described above, when the front of the antenna device on the reflector plate is referred to as the H-shaped arrangement of the vertical polarized wave element and the horizontal polarized wave element. And arranging two or more vertical polarization elements in the vertical direction of the ground, and arranging horizontal polarization elements in the horizontal direction of the ground at the center between the rows and columns of the vertical polarization elements so that the coverage between both the horizontal polarization and the vertical polarization is similar. It is possible to adjust the separation between the two polarizations more than 35㏈, while applying a wireless communication system, a vertical polarization signal corresponding to a relay station or a mobile terminal station is supplied as the main signal (TRx), and the horizontal polarization signal is a mobile terminal It can be used as a diversity reception signal to a station, prevents the reduction of transmission / reception gain, and wireless communication system Is made so that when the coverage overlap hand-over stability, and that to minimize unnecessary overlap the coverage of the quality of the data transmission service of a relatively high antenna designed by the method, and an antenna device as a technical problem.

Hereinafter, a method and apparatus for designing a dual polarized single beam antenna using an H-type element array according to the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

FIG. 2 is a diagram illustrating a device arrangement according to a dual polarized single beam antenna design method using an H-type device array according to the present invention.
In the dual polarized antenna design method according to the present invention as shown in FIG. 2, the most basic technical features are a method of arranging antenna elements in an 'H' type and a binomial in order to secure separation and apply uneven water distribution. Substantial zero is obtained through the corner reflector 76, which is a curved curved surface of a predetermined width and height in the application of disproportionate water distribution such as distribution, triangulation, dolphin-chebyshev distribution, Taylor function distribution, and cosine distribution. There is a characteristic in the method of forming.

Accordingly, the present invention divides an antenna element for transmitting and receiving a double polarization into a vertical polarization element 10 and a horizontal polarization element 20, and in order to arrange the divided antenna elements on the reflector 70, the antenna device facing front side. As a reference, the vertical polarization elements 10 provided with a plurality of the vertical polarization elements 10 in the vertical direction of the ground are arranged in two or more columns 12 and 14, and the rows 12 and 14 are arranged. The horizontal polarization elements 20 arranged in the horizontal direction of the ground are arranged at the center of the vertical polarization element 10 so that the arrangement structure of the vertical polarization element 10 and the horizontal polarization element 20 becomes H type. It is characterized by arranging.

That is, in arranging the antenna elements of the dual polarization antenna, two or more vertical polarization columns 12 and 14 are formed, and horizontal polarization columns 22 are formed between the vertical polarization columns 12 and 14.

According to the embodiment shown in FIG. 2, six vertical polarization elements 10 are arranged in a vertical direction on the reflection plate 70, which is a reflection plane, to form vertical polarization columns 12 and 14. The tear is arranged in two rows 12, 14 to form two vertically polarized strings 12, 14. In addition, as shown in the center position line C, six horizontal polarization elements 20 are arranged for each vertical polarization element 10 between the two vertical polarization strings 12 and 14 so that the horizontal polarization string 22 is formed. To form.

The horizontal polarization element 20 is arranged in a direction orthogonal to the vertical polarization element 10 and vertically disposed between the vertical polarization elements 10 so that the horizontal polarization element 20 is applied to the reflector plate 70. According to the altitude installed and the distance between the vertical polarization element 10, the beam width is adjusted to approximately 35 ° to 70 °.

Although the individual horizontal patterns of the vertical polarization element 10 are circular, the horizontal polarization element 20 has a beam width of the horizontal pattern with respect to the horizontal polarization due to the eight-shaped directivity similar to the case where the vertical polarization string is half wavelength interval. In order to make the beamwidths of the vertical polarization element 10 and the horizontal polarization element 20 similar to each other, as shown in FIG. 3, when the vertical polarization strings 12, 14, and 16 are three, The horizontally polarized columns 22 and 24 are formed between the three rows to form a structure like the letter 'H'.

The vertically polarized elements 10 arranged as described above are installed at a low altitude of 1/4 wavelength or less on the plane of the reflecting plate 70 due to the characteristics of vertical polarization, and the spacing between the vertically arranged vertical polarization columns and columns is about half wavelength. It is possible to reduce the beam width by creating a basic beam width characteristic of 35 ° to 70 °, widening the vertical polarization row spacing and decreasing the altitude, increasing the area of the horizontal polarization element 20 and approaching the vertical polarization element 10. The more the beam width can be installed, the wider the beam width can be.

Therefore, it is preferable to use the vertical polarization string as a means for communicating the main signals Tx & Rx or TRx of the antenna device.

As described above, the antenna elements arranged in the 'H' type are vertically polarized elements 10 of the vertically polarized strings 12, 14, and 16 as illustrated in FIGS. 2 to 3. It is electrically coupled with the vertical polarization output divider 30 coupled with the polarization input / output unit 50 to transmit and receive vertical polarization, and the horizontal polarization elements 20 of the horizontal polarization strings 22 and 24 transmit and output vertical polarization signals. It is electrically coupled with the horizontal polarization output distribution unit 40 coupled with the horizontal polarization input and output unit 60 for transmitting and receiving horizontal polarization.

As described above, the vertical polarized strings 12, 14, and 16 are used as means for transmitting and receiving the main signal, and the horizontal polarized strings 22 and 24 are used as means for transmitting and receiving the auxiliary signal. When used together, the vertical polarization input / output unit 50 becomes a connecting means for providing a main signal, and the horizontal polarization input / output unit 60 becomes a connecting means for providing an auxiliary signal (Diversity).
In addition, the reflector 70 is formed of a dielectric substrate 72 with a portion of a horizontal plane as shown in FIG. 4 for explaining the structure of the reflector according to the method of designing a dual polarized single beam antenna using the H-type element array of the present invention. do.
In this case, the dielectric substrate 72 includes signal distribution units 30 and 40 implemented as distribution circuits on the rear surface opposite to the directing surface, and connects the antenna element to the distribution circuit of the signal distribution unit electrically and fixes the dielectric substrate for fixing. And a soldering fixing hole 74 penetrating 72.
Therefore, the antenna elements 10 and 20 are inserted into the soldering fixing hole 74 in the front surface of the dielectric substrate 72, and the antenna elements 10 and 20 are inserted into and fixed in an 'H' shape through soldering. And electrically connected to the distribution circuit.

That is, the dielectric substrate 72 of the reflector 70 has a reflection function for reflecting a signal, a power supply function for feeding power to the antenna element, and a fixing function for fixing the antenna element.

On the rear surface of the dielectric substrate 72, a vertical polarization output divider 30 and a horizontal polarization output divider 40, which are signal dividers, are formed as distribution circuits, and the vertical polarized output divider 30 is a vertical polarized input / output unit. 50 and the horizontal polarized wave output distribution unit 40 are electrically coupled to the horizontal polarized wave input / output unit 60, respectively.

In addition, the connection part of the antenna element is inserted into the position where the vertical polarization antenna 10 and the horizontal polarization antenna 20, which are antenna elements, are electrically connected to the distribution circuit through soldering and fixed on the dielectric substrate 74. Soldering fixing hole 74 is formed to be.

In this case, as shown in the cross section of FIG. 4, the reason for drilling the signal distribution unit forming part of the distribution circuit of the dielectric substrate 72 is that the front surface of the dielectric substrate 72 fixes the antenna elements and feeds the reflective surface. The back side is to precisely distribute the output, to minimize the length of the wiring, and to be spaced apart from the interferer for the distribution circuit.

The distribution circuit of the signal distribution unit, which is the vertical polarization output divider 30 and the horizontal polarization output divider 40, distributes the output to each of the vertical polarization elements 10 of each of the vertical polarization strings. The ratios can be applied to various non-uniform distribution functions, such as binomial, triangular, Dolphin-Ceviche, Taylor, and cosine.
Accordingly, the signal distribution unit implemented by the distribution circuit distributes the output to each element at an output ratio according to the various distribution functions, and in particular, functions to mathematically suppress the axial signal for implementing the single beam characteristic.

In addition, the reflector 70 described with reference to FIGS. 2 to 3 is illustrated in FIG. 5 for explaining the structure of the reflector on which the corner reflector is formed according to the dual polarized antenna design method of the present invention. A corner reflector 76 inclined at a predetermined height is formed to balance the reception of the vertically polarized element 10 along the outer circumferential surface of the reflector 70.

As shown in FIG. 5, when the outer circumferential surface of the reflecting plate 70, that is, the antenna device is viewed from the front, a corner reflector 76 is formed on the upper, lower, left, and right sides of the reflective curved surface having a predetermined angle and height. .

The corner reflector 76 has + 90 ° and −90 degrees relative to the center of the horizontal plane as the vertical polarization columns 12 and 14 of the antenna elements arranged in the 'H' shape are arranged at horizontal intervals of approximately half wavelength. Theoretically forms a zero point in the direction of °, but it is difficult to form the zero point because the left and right environment of the actual antenna element is different for each of the vertically polarized columns 12 and 14.

Accordingly, the + 90 ° and −90 ° directions are formed through adjustment by actual measurement so that the reflective surface is formed at the edge of the reflector 70 at a predetermined distance and angle, so that the left and right environment is consistent with each of the vertical polarization columns 12 and 14. Compared with Esau's main beam, it can form an extreme zero below -30 dB.

As a result, the transmission signal can be suppressed to all the rear parts by the vertical polarization beam control, so that the use of the vertical polarization as the main signal can significantly improve the actual signal noise ratio in the field of operation.

That is, Figure 6 (a) as shown in the figure for explaining the pattern of the vertical and horizontal polarization array of the antenna device according to the method for designing a dual polarization antenna using the H-type element array of the present invention Comparing the pattern of the vertical polarization of the antenna device according to the design method of the dual polarized antenna through the pattern diagram of the conventional dual polarized antenna device of FIG. 1, the horizontal polarization of the vertical polarization string is half-wavelength interval and the output ratio is evenly distributed. Vertically, it is possible to stabilize the service area by applying the output ratio according to the Dolphin-Chebysev distribution and forming a single forward-oriented beam as compared to the conventional dual polarized antenna device with the beam pattern when SLL = -40 kHz. It can be suppressed with the intensity of about -20㏈ (100 times) or less about the side and the rear, and the performance of the antenna device is seen to be improved. There.

In addition, Figure 6 (b) Dolphin output ratio of the horizontal polarization element of the horizontal polarization string as shown in the figure for explaining the pattern of the horizontal polarization string of the antenna device according to the method of designing a dual polarization antenna through the H-type element array of the present invention The output ratio according to Chebyshev distribution and SLL = 40㏈ is applied in the form of a beam horizontally. Properties appear. Compared with the conventional dual polarized antenna apparatus, the service area can be relatively stabilized by forming a single forward-oriented beam in one row, and has an intensity of about 15 dB or less for the side and the rear compared to the conventional dual polarized antenna apparatus. It can be suppressed that the performance of the antenna device can be seen to be improved.

Accordingly, the horizontal polarization string is preferably used as a diversity antenna of a wireless communication system in order to improve the signal noise ratio in a wireless environment and to adapt to the polarization change of a mobile terminal in real time.

In addition, according to the design method of the dual polarized antenna using the H-type element array, the vertical polarized string and the horizontal polarized string are arranged to be orthogonal to each other in the 'H' shape on the reflector, and at different heights, and between the polarizations by the absorber of the shielded room By suppressing divider crosstalk, two polarization isolations can vary antenna characteristics such as beam width, side ratio, front and rear ratio, and gain while maintaining approximately -35 dB or less.
That is, in the case of the conventional device array, the vertical and horizontal polarizations of the device are facing each other in close proximity, so it is difficult to expect separation between polarizations of more than 15 db. It is difficult to achieve axial signal suppression to realize a single beam because it is difficult to achieve the reception balance of the present invention. However, the present invention provides the above-mentioned unbalanced feeding method by minimizing the interference between devices with polarization separation of more than 35db by arranging the devices in H type. Make it realistic.
