Design of a novel dual-circular polarized based on SIW-CPW coupler
This paper designed a kind of dual-circular polarized antenna based on substrate integrated waveguide structure (SIW). This antenna contains a SIW-CPW coupler and two resonant slot antennas. The coupler uses SIW as the radiation portion while coplanar waveguide (CPW) is the input matching portion that is connected directly to the active circuits, and each resonant slot antenna has six -45° or 45° radiating slots arranged on the broad wall of the radiating SIWs. What is more, the perfect combination of them can realize the function of (LHCP and RHCP). The simulation results show that the antenna has a relative bandwidth over 5.3% (22.1-23.3GHz) under axial ratio bandwidth and the isolation between two channels is higher than 22 dB within frequency band. The realizable gain is 12.2dB.
