宽带法布里-珀罗谐振腔天线
Wideband Fabry-Perot cavity antenna
摘要
Abstract
In order to improve the radiation bandwidth of the Fabry‐Perot Cavity ( FPC) antenna , a new approach has been proposed , namely employing a tapered corrugation structure on the ground plane . To verify the proposed method , a wideband high‐gain FPC antenna is designed . By introducing the corrugation structure , the height of the cavity can be gradually reduced . In this way , the phase of the radiation field can be compensated , which leads to a well‐distributed radiation aperture . Therefore , the 3 dB gain bandwidth can be enhanced . This structure is calculated by the CST Microwave Studio . The results validate the proposed approach , which helps 3 dB gain bandwidth improvement from 17% to 24% . Moreover , the 10 dB impedance bandwidth and the maximum realized gain remain unchanged , that is , 35.7% and 14.7 dBi , respectively . This design can be widely used in many applications , such as wireless communication , due to its relatively wide bandwidth .关键词
