Novel dual-band and dual circularly polarized microstrip antenna

Abstract

This paper presents a novel dual band and dual circularly polarizated microstrip antenna. Simulated and measured results indicate that this antenna has a good performance at 1.268GHz and 1.615GHz with AR<;3dB. As the multi-layer and single-fed structure is employed to simplify the complexity of the antenna, it can be a candidate in satellite positioning and communication systems.
