摘要：

Fabry-Perot cavity (FPC) antennas are fully integrated onto a printed circuit board. The antenna consists of a partially reflective sheet formed by finite-size periodic array of metal patches printed on a grounded dielectric substrate and a feeding microstrip patch embedded in the substrate. The field distribution reveals the basic features of operating modes and the distribution of power loss. Simulated and measured results of the proposed antennas operating at 10 GHz show the realized gain of 15 dBi with an aperture of 2x2 the operating wavelength in free space. Moreover, the proposed antenna realizes circularly polarized radiation. The study shows that such fully dielectric-integrated planar FPC antennas are able to provide high gain and circular polarization operation function with low profile, easy integration onto circuit board, and mechanical robustness, suitable for low-cost mass production.
