Abstract:The development of the circularly polarized ceramic patch antennas is discussed.The patch antenna is designed by method Cavity model and coaxial feed mode,and made from dielectric ceramic materials with the dielectric constant being 38 of the antenna,the center frequency is 1678.13 MHz and bandwidth 15 MHz.The test results show that the antenna meets the performance requirements of Beidou Navigation Satellite System in China.
Key words:patch antennas; ZST ceramic; design principle; circular polarization
