Abstract
A high gain Fabry-Perot cavity antenna (FPCA) designed by modified ray tracking model(MRTM) is presented in this paper. In particular, the conventional ray tracking is modified in order to calculate the electric field distribution on the partially reflective surface(PRS). Furthermore, the dependence of the magnitude of PRS reflection coefficients on aperture efficiency is studied, which shows that an optimal magnitude exists on aperture efficiency for a fixed size FPCA. By using the optimized reflection coefficient, a final compact single layer FPCA with a dimension of 6.25λ0 × 6.25λ0 and a profile of 0.5λ0 is designed. The proposed antenna can reach a peak gain of 24.0dBi at 12.5GHz and an aperture efficiency of 51.2%.
