摘要：

As is well known, the global navigation satellite system (GNSS) antenna always suffers from the size problem. The authors' propose that two shorting probes in parallel are loaded on a patch antenna and a dual-band compact GNSS antenna, which has a smaller electrical size of only 60 mm (0.23) x 60 mm x18 mm (0.07) x ( being the wavelength in free space). A dual-layer feed network is also designed to achieve circular polarised radiation. Simulated and measured results show that the proposed antenna has good and stable performance over both dual operating bands.
