Abstract

A bandwidth reconfigurable planar antenna for WLAN/ WiMAX applications is proposed. The proposed antenna consists of a rectangular radiation patch with a narrow vertical slot and an L-shaped slot, a ground plane and a microstrip feed-line. Two PIN diodes are attached in the middle of the L-shape slot. They are used to control the current flow on the radiation patch. Therefore, the bandwidth reconfigurability is enabled by switching the operating states of PIN diodes. The impedance bandwidth ranges from 22% to 78%. The agreement between simulated and measured results validates the proposed design.

用于WLAN/WiMAX应用的带宽可重构平面天线

提出了一种用于WLAN/ WiMAX应用的带宽可重构平面天线。该天线由带窄垂直槽和l型槽的矩形辐射贴片、接地面和微带馈线组成。两个PIN二极管连接在l形槽的中间。它们被用来控制辐射贴片上的电流。因此，带宽可重构性是通过切换PIN二极管的工作状态来实现的。阻抗带宽范围为22% ~ 78%。仿真结果与实测结果吻合，验证了设计的正确性。
