摘要
Abstract
This paper proposes a broadband double-layer rectangular microstrip antenna(DL-RMSA) fed from the non-radiating edge of a bottom patch. The characteristics of the antenna has been analyzed via simulation tool. This design shows that cutting 3 to 5 slots along the co-polarization into the parasitic patch can effectively suppress the cross polarization radiation as well as enhances the impedance bandwidth. As compared to the conventional DL-RMSAs, the proposed antenna presents a 30% broader impedance bandwidth) while maintaining the cross polarization level. Using this antenna as an element in the construction of a corresponding array can simply the feed network and yield a co-planar-fed microstrip array with broad operation bandwidth, high radiation efficiency and wide-angle scanning capability. A X-band demo array of 8 X 8 elements has been fabricated and tested. The measurement results show that this array antenna exhibits low cross-polarization level and high radiation efficiency within a relative bandwidth of 17. 6%.关键词
