Paster antenna according to the present invention is the paster antenna of the non-square patch antenna of SMT type, this paster antenna has the structure that conduction Figure 62 is extended to two sides of the side with longer medium block 61, and this structure is identical with the structure of the paster antenna of aforesaid the 4th execution mode.
For this paster antenna, the inside in input/output terminal 63 and hole 64 all applies with silver, rather than the 4th feedback pin 53 usefulness silver in the execution mode apply, thereby the conductive plane 62 on input/output terminal 63 and top is electrically connected, the conduction Figure 62 that is made from silver simultaneously pass medium block with lead to the bottom by the ground plane 65 formed of electric conducting material, thereby SMT can be used to provide paster antenna.
Fig. 8 is the schematic diagram according to the 6th execution mode of the non-square patch antenna of ceramic dielectric block of the present invention.
Paster antenna according to the present invention is the non-square patch antenna of SMT type, this paster antenna has the structure that conduction Figure 72 is extended to two sides of the side with longer medium block 71, and this structure is identical with the structure of the paster antenna of aforesaid the 4th execution mode.

For non-square patch antenna, can obtain circular polarization characteristics by on width ceramic block different and medium block, forming conductive pattern with length according to the ceramic dielectric block according to the 4th execution mode or the 6th execution mode of the present invention.
On the other hand, the non-square patch antenna of ceramic dielectric block also is an antenna of comparing miniaturization with traditional square patch antenna, wherein since the characteristic of the linearly polarized wave of this non-square patch antenna of scaling of conductive pattern be enhanced, simultaneously it can be installed in use machine inside and also have the advantages that receptivity is enhanced.
In addition, biobelt wide can be designed different with square patch antenna.Especially, have under the situation of circular polarization characteristics, because miniaturization is possible when keeping the receptivity of conventional patch antenna,, and can bring the advantage of the less circular polarization of polarization loss in having a frequency of timing alignment so two or more channel can be received and dispatched.
Fig. 9 is the schematic diagram according to the 7th execution mode of the non-square patch antenna of ceramic dielectric block of the present invention.
For paster antenna according to the present invention, realize conduction Figure 78 on the top of medium block 76 with different length-breadth ratios, wherein conductive pattern one or more grooves of being moved to two sides of the side with shorter length are formed in this conduction Figure 78.
In the conductive pattern of removing a side with shorter length, groove is replenished, the narrowed width of conductive pattern is to 13mm or littler, so that other linearly polarized antenna characteristics in the 1.8GHz bandwidth move and become similar to the other linear polarization wave property of low frequency.Therefore, for each linearly polarized antenna characteristic, frequency and size, phase angle change 90 degree, thus shown circular polarization characteristics.
Especially, have under the situation of circular polarization characteristics, because conductive pattern the longitudinal axis can be reduced the media ceramic piece on implement, and when having the receiving quality of traditional paster antenna, maintenance has high quality factor characteristic (quality characteristic of Q*f=material), so the advantage that the polarization loss in the polarization characteristic reduces is revealed.In addition, this paster antenna has the noise characteristic better than square antenna.
In addition, as shown in figure 10, to use dielectric constant be 30 or be higher than 30 high dielectric constant materials at ceramic dielectric block 76a, and the shorter side in the ceramic dielectric block 76a of non-square type fully is longer than 12mm or when longer, even it is different with Fig. 6, though this paster antenna does not have to form conductive pattern on the side surface of ceramic dielectric block 76a or groove, and the groove in the conductive pattern of the shorter side that is removed is not present in the conductive pattern 78a that is arranged on the non-square ceramic dielectric block 76a yet, because the conductive pattern 78a of upper surface, this non-square ceramic dielectric block 76a also can have circular polarization characteristics.
The paster antenna of the groove of constructing in conductive pattern is not limited to aforesaid specific implementations, but these paster antennas can be applied to second execution mode to the, six execution modes.Therefore, can use the various forms of the non-square patch antenna of feedback pin type or SMT type to realize circular polarization characteristics.Especially, the non-square patch antenna that conductive pattern can be extended to the side surface of medium block such as 13 * 18mm or 13 * 20mm can be realized circular polarization characteristics.
Yet, for as the very long paster antenna of length of the side of 13 * 25mm, preferably,, simultaneously conductive pattern is extended to side surface and realizes circular polarization characteristics by on the conductive pattern on top, slotting.
For paster antenna according to first execution mode to the, six execution modes, because as the width of the use machine of navigation system, be that 13mm and width are 18～35mm or 35mm or when longer in the length of paster antenna, can realize linear forms.So this paster antenna can be installed in the inside of the machine of use.
In addition, when the size a side reduces, can improve Q*F by using high-k less than Er60.For example, for the paster antenna of 13 * 18mm, can use relative dielectric constant be 45 and Q*F be higher than 40000 ceramic powders.For the paster antenna of 13 * 20mm, can use Q*F be 35000 and relative dielectric constant be 37 ceramic powders.Like that, the loss of raw material just can reduce, and the gain of antenna can improve, and comparing receptivity with traditional square patch antenna also is good.
Below, with reference to figures 11 to Figure 23, comprise that the execution mode of antenna integrated module of the non-square patch antenna of ceramic dielectric block will be described in detail.
Figure 11 is first execution mode according to antenna integrated module of the present invention.
For integrated paster antenna according to this execution mode, the non-square patch antenna 81 of ceramic dielectric block and low noise amplifier 82 are adhered to by SMD (surface mount device) method on the same plane of PCB 83 of long narrow rectangular shape, and connect the transmission line 84 that satellite-signal is transferred to engine from described low noise amplifier 82, wherein in the SMD method, device is adhered on the PCB, not drilling on PCB, and lead is printed on this PCB when the lead dissolving that will be used for installing automatically.
According to the present invention, for the antenna integrated module that is of a size of 65 * 10 * 4.7mm, paster antenna 81 only is arranged in the part that width is 13mm.Compare with square patch antenna, this antenna integrated module has shown that length is by the characteristic of elongated and narrowed width.By on the same plane of PCB, implementing the height that paster antenna and low noise amplifier reduce antenna, use the indoor design of machine to be modified.
Figure 12 is the block diagram representation that is used for the low noise amplifier of antenna integrated module according to of the present invention.
For the circuit 82 of low noise amplifier, after the satellite-signal that receives from the non-paster antenna 81 according to ceramic dielectric block of the present invention was carried out first amplification 8202, satellite-signal passed through band pass filter 8204, and carried out second subsequently and amplify 8206.Finish second amplifying signal and be transferred to the GPS engine by stube cable.
Because the antenna of the high-k that can use in Anneta module is owing to miniaturization has the narrower problem of bandwidth, thus low noise amplifier be used for that satellite-signal is amplified to the satellite-signal of reception can be in the processed degree of GPS engine.
