| 摘 要： | 该文介绍了一种宽带高增益的E型天线,该天线以空气为介质,通过采用L型探针耦合馈电,贴片与接地板之间可以用塑料杆或泡沫块支撑。馈线通过激励一金属片后,形成L型探针,实现容性耦合,达到激励天线的目的。该天线结构简单。天线在驻波比小于2时,相对带宽达到了41%,可适用于数字通信系统、IMT-2000、无线局域网等无线应用系统,最大增益可达7.52dBi。

| Abstract: | This paper describes a wide-band and high gain E-shape antenna,choose the air as substrate,the antenna can be coupled though L-shape probe which excited by a coaxial probe directly.With a plastic or foam blocks to support between the patch and ground,L-probe can be formed through a sheet metal to feed,and achieve capacitive coupling,so it can feed the antenna.The antenna has a simple structure.The antenna finds an impedance bandwidth of 41% for which can cover the DCS,IMT-2000,2.4 GHz WLAN applications. |
