摘要：
This paper proposes a compact polarization microstrip antenna based on double-layer structure. The bandwidth of the whole antenna is widened by expanding the top and bottom layers respectively. After the design of antenna structure and adjustment of size, the proposed antenna can achieve both the left- and right-hand circular polarizations in 2.33 GHz-2.97 GHz. Measurement results indicate that the effective bandwidth is 640 MHz in S-band and the relative bandwidth can achieve 24% with S11 less than -15 dB. © Tianjin University and Springer-Verlag Berlin Heidelberg 2012.
