Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
Fig. 1 shows the overall structure schematic diagram of one embodiment of the invention, with reference to shown in Figure 1, one embodiment of the present of invention are a kind of dual polarization E type patch antenna elements with parasitic disk, be provided with top dielectric plate 1 and layer dielectric plate 7 in this antenna element, described top dielectric plate 1 is supported and is placed the top of layer dielectric plate 7 by at least three plastics screws 6; Go out as shown in Figure 1, the plastics screw is set to four herein, and is distributed near four angles of top dielectric plate 1 and layer dielectric plate 7.
With reference to figure 2, Fig. 3 and shown in Figure 4, up and down two surfaces of described top dielectric plate 1 are printed on respectively the E type paster 3 of the E type paster 2 of fluting direction-45 ° and fluting direction+45 °, the E shape paster 2 of described fluting direction-45 ° links to each other with probe 4, and the E shape paster 2 of fluting direction-45 ° by itself circular hole 14 and probe 5 between keep the gap.Similarly, the E type paster 3 of described fluting direction+45 ° links to each other with probe 5, and the E type paster 3 of fluting direction+45 ° by itself circular hole 13 and probe 4 between keep the gap.
With reference to figure 2, Fig. 3 and shown in Figure 5, the upper surface of described layer dielectric plate 7 is printed on circular patch 9, and lower surface all covers copper as metallic reflection plate 8, and the circular hole on the circular patch 9 (10) and circular hole (11) are so that all keep the gap between circular patch 9 and probe 4 and the probe 5.The size of described metallic reflection plate 8 is the same with the lateral dimension of antenna.
Based on above-described embodiment, one of key technology means of the present invention are to have introduced circular hole 10, circular hole 11, circular hole 13 and circular hole 14.The diameter of described circular hole 10 and circular hole 11 is all greater than two through-hole diameter sizes on the top dielectric plate 1, and two through-hole diameters sizes on the top dielectric plate 1 and probe 4 and probe 5 is the same.The diameter of described circular hole 13 and circular hole 14 is big or small the same with two through-hole diameters on the layer dielectric plate 7, and two through-hole diameters sizes on the layer dielectric plate 7 are the same with coaxial probe outer conductor diameter.Such structure is not so that directly connect between probe 4 and the probe 5, is not easy to change direction so that pass through the path of the electric current that each probe flows to, thus the polarization purity when having improved each port feed.
With reference to shown in Figure 2, the orthogonal thereto state of E type groove of the E type paster 3 of the E type paster 2 of fluting direction-45 ° and fluting direction+45 ° its objective is that the polarised direction that each port is produced is vertical.The length of adjustment tank can be improved the beamwidth of antenna and increase cross polarization isolation.E shape paster 3 based on the E shape paster 2 of the aforementioned fluting direction-45 of mentioning ° and fluting direction+45 °, the execution mode that is more preferably is that the rectangular strip in the middle of them is blocked sub-fraction, be used for reducing current path, two are truncated the in different size of part, can be optimized for the impedance matching of each port.Further, E shape paster 3 based on the E shape paster 2 of the aforesaid fluting direction-45 of mentioning ° and fluting direction+45 °, around each E type paster all by etc. big or small corner cut, be used for reducing size, it is in different size that but the corner cut of E shape paster 2 is compared with the corner cut of E shape paster 3, also can be optimized for the impedance matching of each port.
Based on the above embodiment of the present invention, further preferred technical scheme is to introduce circular patch 9, this is equivalent to loading capacitance, reduced the resonance frequency of antenna, so that the working frequency range of antenna is moved toward low frequency, thereby reduced the size of antenna.Because antenna structure is asymmetric, the center of circular patch does not need to aim at the center of antenna yet, can adjust the cross polarization characteristics that Antenna Impedance Matching and antenna are improved in its position.
With reference to shown in Figure 3, the present invention is on above-mentioned basis for the embodiment that the technical solution problem is more preferably, because probe 4 is to link to each other with the E type paster 2 of fluting direction-45 °, so can directly weld at top dielectric plate 1 upper surface, but probe 5 is to link to each other with the E type paster 3 of fluting direction+45 °, to weld at the lower surface of top dielectric plate 1, difficulty of processing is a bit large because antenna is too thin, for addressing this problem, probe 5 can be by the upper surface welding of metallization via hole 12 in top dielectric plate 1, and its pad can not link to each other with the E type paster 2 of fluting direction-45 °, thereby so that probe 5 links to each other with the E shape paster 3 of fluting direction+45 °, this is so that the processing of antenna becomes simple.
The antenna running is: when with the dual polarization E type paster antenna of parasitic disk during at+45 degree polarization port feed, when microwave signal is entered by probe 5, electric current is by ° E type paster 3 transmission of fluting direction+45, electric current is along E type groove Flow Structure Nearby, and its Energy Coupling is to fluting direction-45 ° E type paster 2 and circular patch 9.Fluting direction-45 ° E type paster 2 and circular patch 9 have formed a distributed circuit circuit, and they provide the inductance capacitance component, have reduced the resonance frequency of antenna.The effect of metal floor 8 is the energy that reduce backward radiation, and most of energy is all to previous irradiation when making antenna work.
The present inventor is in its experimentation, based on inventive concept design with the contrast of the dual polarization E type patch antenna element return loss measured result of parasitic disk and simulation result with reference to shown in Figure 6, can be found out in return loss by simulation result to be lower than-situation of 15dB under, port one actual measurement relative bandwidth is 7.7%(2.48GHz-2.69GHz), port 2 actual measurement relative bandwidths are 7.7%(2.48GHz-2.69GHz).Measured result and simulation result coincide better.
Further, based on thought of the present invention design with the contrast of the actual measurement isolation of the dual polarization E type patch antenna element two-port of parasitic disk and simulation result with reference to shown in Figure 7.Can be found out that by measured result in the whole frequency range of 2.5GHz-2.69GHz, isolation is lower than-30dB.Measured result and simulation result coincide better.
When with the dual polarization E type paster antenna of parasitic disk during at+45 degree polarization port feed, the directional diagram that records at centre frequency 2.6GHz comprises E face main pole, the cross polarization of E face, H face main pole and the cross polarization of H face with reference to shown in Figure 8.Can be found out that by directional diagram the cross polarization level of E face and H face all is lower than in normal direction-25dB.
