摘要
本文设计了一种频率可重构的单极子天线.天线由一个阶梯型馈线、两个L型枝节和一个矩形接地板组成.两个理想开关加载在馈线与枝节之间,通过控制开关状态改变天线的表面电流分布,从而实现频率可重构.天线的尺寸为35mm×40mm.仿真和测量结果表明:该天线可以在两个单频模式(2.4GHz和5.2GHz)以及一个双频模式(2.4GHz/5.2GHz)之间切换.天线在不同模式下都具有稳定的辐射方向图.
This paper presents a frequency-reconfigurable monoole antenna. The antenna consist of a stepped microstrip feed line, two L-shaped stubs and a rectangular ground plane, and two ideal switches are loaded between microstrip feed line and stubs. By changing the states of the switches, the current distribution will be altered, and then frequency reconfigurability is achieved. The overall size of the an- tenna is 35 mm × 40 ram. The simulated and measured results show that the proposed antenna can op- erate at two single-band modes (2. 4 GHzand 5. 2 GHz) and a dual-band modes (2. 4 GHz/5. 2 GHz). The proposed antenna has a stable radiation patterns in different modes.
