Refer to Figure 1A to Fig. 1 C, Figure 1A is the embodiment of the present invention one microstrip antenna transceiver 10
Front schematic view, Figure 1B is the schematic rear view of microstrip antenna transceiver 10, and Fig. 1 C is microstrip antenna
Transceiver 10 is along the schematic cross-section of the hatching line A-A ' of Figure 1A.Microstrip antenna transceiver 10 includes one
Substrate 100, one grounded metal sheet 110, Anneta module 120, switch element 136,138 and micro-strip
Line 146,148.Switch element 136,138 is positioned at the one side of substrate 100, and grounded metal sheet 110
And Anneta module 120 is then positioned at the another side of substrate 100, and grounded metal sheet 110 is arranged at antenna mould
Between block 120 and substrate 100.Anneta module 120 includes dielectric layer 122, radiation sheet metal
124, vertical polarization load point 126 and a horizontal polarization load point 128.Dielectric layer 122 is used for isolating
Grounded metal sheet 110 and radiation sheet metal 124.Radiation sheet metal 124 is major radiator, and it can make
Electromagnetic wave resonates along vertical direction X or horizontal direction Y, and gives off a vertical polarization signal SV
With a horizontal polarization signals SH.Being shaped as of radiation sheet metal 124 is symmetrical in the one of an axis of symmetry XS
Hexagon, is more precisely that a rectangle is clipped two diagonal angles and formed rescinded angle CH1, CH2, in order to control
Energy conversion between vertical polarization signal SV and the horizontal polarization signals SH of Anneta module 120.And
And, radiation sheet metal 124 includes pattern slotted eye SL1, SL2, is used for adjusting vertical polarization signal SV
With the relative phase of horizontal polarization signals SH, to synthesize a right-hand polarized signals or a left-hand polarized signals.
Wherein, pattern slotted eye SL1, SL2 are respectively symmetrically in axis of symmetry XS, and are respectively arranged at vertical polarization
Load point 126 and the both sides of horizontal polarization load point 128.
Additionally, vertical polarization load point 126 and horizontal polarization load point 128 are also symmetrical in axis of symmetry XS.
Microstrip line 146 is electrically connected to vertical polarization load point 126 via an opening 106 of substrate 100 and opens
Close between element 136, and control Anneta module 120 by switch element 136 and transmit or receive vertical
Polarized signal SV.Microstrip line 148 is then electrically connected to level pole via an opening 108 of substrate 100
Change between load point 128 and switch element 138, and control Anneta module 120 by switch element 138
And transmit or receive horizontal polarization signals SH.Wherein, the length of microstrip line 146,148 is the most vertical
