摘要：
In this article, a dual circular polarized antenna fed by double quadrature couplers is presented. The proposed structure consists of three parts: dual-polarization antenna, quadrature couplers, and connection structure. This structure is not sensitive to orientation due to its circular polarization. The antenna gain can be easily increased by cascading orthogonal dipoles. Therefore, this array structure has a fan beam circular polarized radiation pattern. This structure is fabricated on the Rogers 4003C substrate. The simulation and measurement results show that this proposed antenna achieves return loss above 10 dB in the frequency range of 9.8-10.2 GHz.
