A Dual-band Circularly Polarized Antenna with Novel Feeding Method for BDS, GPS and GLONASS Application

摘要：

　　In this paper,a dual-band circularly polarized antenna is proposed.This antenna constructs with two layers,which provides two working frequency bands.One of the bands operates at the BDS B3(1268.52±10 MHz).The other band concludes the GPS L1(1575.42±10 MHz)and GLONASS L1(1602±8 MHz).By changing the length and width of four slots on each patch,its circular polarization performance and working bandwidth can be adjusted.The multistacked patches fed through two coaxial probes which provide two different input signal.To the probe feed on the lower patchit do not connect direct to the lower patch but solder to a small disc on the upper patch.By adjusting these parameters,we will obtain better impedance matching performance.
