Abstract :
A dual-band circle polarization microstrip antenna at 1.57GHz and 2.45GHz is presented. We adopt double patch model and feed the top patch through the coaxial feed. Cutting angle and choosing appropriate feeding point was adopted to realize circular polarization of the two patches. The down patch can obtain a good match by moving the top patch. The performance change of the antenna by moving the top patch is the key analyze of this paper. The simulated and measured results show that the proposed antenna has a good circularly polarized radiations.
