The antenna assembly of the embodiment of the present invention, by using in horizontal polarization directions the first antenna of radiated electromagnetic wave, for the second antenna of radiated electromagnetic wave in vertical polarization directions and the power governor for adjusting the power of first antenna and the power of the second antenna respectively, so that first antenna and the power ratio of the second antenna reach setting value, so as to improve omnidirectional's coverage of antenna.
Fig. 2 is a kind of schematic diagram for antenna assembly that the embodiment of the present invention two is provided.As shown in Fig. 2 the antenna assembly 1 includes：First antenna 10, the second antenna 11 and power governor 12.
Specifically, power governor 12 includes：First match circuit 20, the second match circuit 21 and signal source 22.
Further, the first match circuit 20 is used to adjust the impedance value of first antenna 10 to change the power of first antenna 10；Second match circuit 21 is used to adjust the impedance value of the second antenna 11 to change the power of the second antenna 11；Signal source 22 is used for the first match circuit 20 and the power output of the second match circuit 21, for above-mentioned two circuit normal work.
Further, the first match circuit 20 includes：First inductance 200, the first tunable capacitor 201, the second tunable capacitor 202, the second inductance 203, the 3rd inductance 204.
Further, the second match circuit 21 includes：4th inductance 210, the 3rd tunable capacitor 211, the 4th tunable capacitor 212, the 5th inductance 213 and the 6th inductance 214.
Further, the first end of first inductance 200 is electrically connected with first antenna 20, second end of the first inductance 200 is electrically connected with the first end of the first tunable capacitor 201 and the first end of the second tunable capacitor 202 respectively, the second end ground connection of the first tunable capacitor 201（Ground, guide number D)；Second end of the second tunable capacitor 202 is electrically connected with the first end of the second inductance 203 and the first end of the 3rd inductance 204 respectively, the second end ground connection of the second inductance 203, and the second end of the 3rd inductance 204 is electrically connected with signal source 22.
Further, the first end of 4th inductance 210 is electrically connected with the second antenna 21, second end of the 4th inductance 210 is electrically connected with the first end of the 3rd tunable capacitor 211 and the first end of the 4th tunable capacitor 212 respectively, the second end ground connection of the 3rd tunable capacitor 211；Second end of the 4th tunable capacitor 212 is electrically connected with the first end of the 5th inductance 213 and the first end of the 6th inductance 214 respectively, the second end ground connection of the 5th inductance 213, and the second end of the 6th inductance 214 is electrically connected with signal source 22.
Specifically, the purpose for the coverage for changing antenna assembly 1 according to the actual requirements by the power governor 12 in said antenna device 1, can be reached.First match circuit 20 is connected in series as tie point with first antenna 10, second match circuit 21 and the second antenna 11 are connected in series as the second branch road, the power output of signal source 22 is constant, it is equal with the voltage of guarantee tie point in parallel and the second branch road two ends, it can be seen from circuit theory, now tie point and the power of the second branch road are inversely proportional with its impedance value, due in practice, the own impedance of the antenna 11 of first antenna 10 and second is constant, therefore, can be by adjusting the resistance of the first match circuit 20 and the second match circuit 21
Anti- value so that the power ratio on the antenna 21 of first antenna 20 and second reaches the ratio required for actual coverage.For example, it is actually needed and covers 450 meters in the horizontal direction with the antenna assembly 1, it is 9 that the ratio between the coverage of 50 meters, i.e. horizontal direction and the coverage of vertical direction are covered in vertical direction:1, can be by the way that the power ratio of the antenna 11 of first antenna 10 and second be adjusted into 1 it was found from description above:9, reach above-mentioned coverage.Because antenna has own impedance, assuming that the own impedance of first antenna 10 is 50 ohm, the own impedance of second antenna 11 is also 50 ohm, the impedance of first match circuit 20 can be adjusted to 160 ohm, so that the impedance in the tie point that the first match circuit 20 is composed in series with first antenna 10 reaches 210 ohm, simultaneously, the impedance of second match circuit 21 can be adjusted to 20 ohm, so that the impedance on the second branch road that the second match circuit 21 and the second antenna 11 are composed in series reaches 70 ohm, then when the power output of signal source 22 is constant, the ratio between impedance due to tie point and the second branch road is 3:1, therefore, it is 1 to flow through the ratio between electric current of above-mentioned two branch road:3, and first antenna 10 is identical with the own impedance of the second antenna 11, thus the antenna 11 of first antenna 10 and second power sharing ratio be electric current square the ratio between 1:9, so as to will pass through regulation power governor 12 so that the power sharing ratio of the antenna 11 of first antenna 10 and second reaches 1:9, so as to realize that above-mentioned vertical direction is in 1 with horizontal direction:9 antenna covering.Certainly, in practice, even if the impedance of regulation above-mentioned two branch road, reaches 3:1, but due in actual applications, also need the transmission coefficient of consideration antenna, therefore, can be according to the actual transmissions coefficient of the antenna 11 of first antenna 10 and second, above-mentioned two match circuit is finely adjusted again so that the power sharing ratio of the antenna 11 of first antenna 10 and second reaches 1:9.
It should be noted that, in practice, can also using power governor 12 as antenna a part, specific to Fig. 2, i.e. using the first match circuit 20 as first antenna 10 a part, using the second match circuit 21 as the second antenna 11 a part.Still by taking above example as an example, horizontal direction and vertical direction 1 are now if desired reached:9 coverage, because the impedance of first antenna 10 is its own impedance and the impedance value sum of the first match circuit 20, the impedance of second antenna 11 is its own impedance and the impedance sum of the second match circuit 21, therefore, it is 9 only to need the own impedance plus the impedance sum of the first match circuit 20 and the own impedance of the second antenna 11 of first antenna 10 plus the impedance sum of the second match circuit 21:1, therefore, the impedance of first match circuit 20 can be adjusted to 670 ohm, the impedance sum for making itself and first antenna 10 is 720 ohm, the impedance of second match circuit 21 is adjusted to 30 ohm, the impedance sum for making itself and the second antenna 20 is 80 ohm, so that the ratio between impedance of the antenna 11 of first antenna 10 and second is 9:1, thus power thereon
The ratio between be 1:9, so as to reach horizontal direction and vertical direction 1:9 coverage.
Specific to practical devices, the tunable capacitor in the above-mentioned matching network 21 of first match circuit 20 and second can be arranged by matrix form electric capacity, connected and realized by multiple small capacitances.
Because the antenna 11 of first antenna 10 and second is when being used alone, each antenna has respective directional diagram, and its respective directional diagram can all have dead angle, by using the antenna of two different polarised directions, the problem of its respective coverage direction figure has dead angle can be solved, so as to realize omnidirectional's covering of antenna.Also, due to there is power governor 12, thus power adjusting can be carried out to the antenna 11 of first antenna 10 and second according to actual needs, so as to reach the coverage for more meeting physical condition.
