基于互补源的紧凑型圆极化倾斜波束天线
Theory of complementary source and its application to compact circularly polarized tilted beam antenna
摘要
Abstract
In this research study, a compact circularly polarized antenna with a tilted beam is proposed on the basis of a pair of orthogonally oriented complementary dipoles. The proof-of-concept demonstrates that the proposed antenna mainly consists of a planar sectorial monopole antenna, shorting pin, and L-shaped ground plane.The shorting pin connects the monopole and the horizontal part of the ground plane to realize a loop antenna. Experimental results show that a maximum radiation gain occurs at the direction of θ = 60°, φ = 90°, and an axial ratio at values lower than 3 dB is approximately 6. 2％. More importantly, by comparing the proposed antenna with existing circularly polarized tilted beam counterparts, it can be seen that the proposed one is more compact, which fulfills the requirement of miniaturization.关键词
