Embodiment one
An embodiment of the present invention provides a kind of difference bimodulus dual polarization medium resonator antennas, referring to Fig. 2, including：Reflection
Ground 2, the dielectric resonator 3 being arranged on reflectingly 2, multiple conformal metal straps 4 (referring to Fig. 3) and (ginseng of multiple probes 5
See Fig. 3).
Dielectric resonator 3 may include：Central part 31 and 31 surrounding of centrally disposed part and with 31 phase of central part
Multiple foliage portions 32 even are provided with multiple conformal metal straps 4 (referring to Fig. 3) on the surrounding side wall of central part 31, often
One foliage portion 32 of sandwiched between a adjacent conformal metal strap 4 offers multiple coaxial apertures 1 on 2 reflectingly, each to visit
Needle 5 is connected by coaxial aperture 1 with corresponding conformal metal strap 4.
It should be noted that the dual polarized antenna of traditional differential feed has obtain higher than the dual polarized antenna of end fed
More isolations, the reason is that difference excitation can form one virtually on the plane of symmetry of load(ing) point, this can virtually inhibit
Crisscross pattern, to greatly improve isolation.But this conclusion is in the case where being coupled between not accounting for port
Analysis.In fact, the coupling between feed port has prodigious influence for isolation.Improve isolation, it is also necessary to protect
The coupling demonstrate,proved between port is small as possible.
In the present embodiment, by the way that dielectric resonator 3 is arranged to 31 surrounding of central part 31 and centrally disposed part
And the multiple foliage portions 32 being connected with central part 31, and multiple conformal gold are provided on the surrounding side wall of central part 31
Belong to tape 4, each one foliage portion 32 of sandwiched between adjacent conformal metal strap 4, feed port adjacent in this way (including
Conformal metal strip 4 and probe 5) it can be kept apart by foliage portion 32, the coupling between feed port can be effectively reduced, and then further
Improve the isolation between differential bipolar medium resonator antenna port.
Furthermore, it is necessary to which explanation, a usual dielectric resonator resonance have numerous mode resonances in different frequencies
On, as shown in Figure 1, dielectric resonator is placed on differential feed port, the electric field of some patterns is distributed at port in reverse phase,
The electric field of some patterns is in same distributed mutually, under normal circumstances, reverse phase and pattern meeting on frequency spectrum with phase field distribution at port
Occur successively.End fed mode can encourage this two quasi-mode simultaneously, but differential feed can only encourage at port and be in
The pattern of reverse phase distribution, which increase differential feed modes by encouraging multiple patterns to carry out the difficulty of bandwidth enlargement simultaneously
Degree.
In the present embodiment, when four foliage portions 32 in dielectric resonator 3 are apart from each other, mutual coupling
Very weak, at this moment there are one the central part 31 that pattern (i.e. first mode is denoted as Mode1) electric field concentrates on resonator, this group of moulds
The field intensity of formula is as shown in Figure 4 every the distribution map of 90 ° of time phases.In Mode 1, medium resonator antenna it is humorous
Vibration frequency (i.e. Frequency in Fig. 6) mainly determines by the size of a (referring to Fig. 2), a in relationship between the two such as Fig. 6>
It is shown when 12mm；As shown in fig. 7, the resonant frequency (i.e. Frequency in Fig. 7) of medium resonator antenna and b (referring to Fig. 2)
Size relationship it is little.When four foliage portions 32 are close to each other, the coupling enhancing between them, resonant frequency this moment is not only
It is only dependent upon a, is also influenced by other parameters, the resonant frequency is with its variation tendency of the increase of a and before on the contrary, such as a in Fig. 4
<It is shown when 12mm.
Above-mentioned medium resonator antenna, also another pattern (i.e. second mode is denoted as Mode2) is in central part 31
The exchange that energy is carried out between four foliage portions 32 is shown in Fig. 5 every 90 ° of time phase its field distribution variations.In the second mould
In the case of formula, is driven by the energy of central part 31 and generated.The size relationship of resonant frequency and a under second mode is little,
It is mainly determined by the size of b, as shown in Figures 6 and 7.
From Fig. 4 and Fig. 5 it is found that the electric field of the two patterns is distributed along y-axis, indicate that they can be by a pair along y
The differential signal of axis encourages.
In addition, can be seen that the resonant frequencies of the two patterns from the variation tendency in Fig. 6 and Fig. 7, there is mutual shadows
It rings, main reason is that the lap between foliage portion 32 and central part 31 makes two patterns intercouple.Two
The coefficient of coup (i.e. Coupling coefficient in Fig. 8) and the size c (referring to Fig. 2) of lap between pattern are determined
Fixed, the relationship result of study between the two is as shown in Figure 8.
Because of the symmetry of structure designed by difference bimodulus dual polarization medium resonator antenna, also deposited in dielectric resonator 3
In one group and the rp mode of 2 degeneracy of Mode 1 and Mode, their electric field is vertical with the electric field of Mode 1 and Mode 2, along x
Axis is distributed.This group of pattern can be used for designing the difference with low-cross polarization and bandwidth enlargement together with Mode 1 and Mode 2
Bimodulus dual polarization medium resonator antenna.
Optionally, referring to Fig. 2 and Fig. 3, dielectric resonator 3 may include：The central part 31 of rectangular cross-section and four
Foliage portion 32, four foliage portions 32 are separately positioned on the four corners of central part 31.Preferably, the section of foliage portion 32
For rectangle.
