| Popis: | A low cost dual-band shorted annular ring patch antenna is presented for the application of GNSS reception with interference rejection at the horizon. It is shown that the antenna can achieve circular polarization with a single feed pin using two shunted stubs along the inner wall of the ring. The effect of the shunted stubs on the antenna resonance is analytically derived and verified through simulations. The dimensions of the annular ring were designed to create a deep null in the RHCP gain pattern at the horizon and around all azimuth. Additionally, a novel feed configuration is presented using a coplanar waveguide transition to improve impedance matching for the LI and L2 GPS frequencies. |
