摘要

提出了一种平面频率可重构天线。该天线源自矩形微带贴片天线，它由靠近主辐射器辐射边缘的三个寄生贴片组成。集成了PIN二极管，以在主散热器和寄生片之间提供必要的电气连接。通过设置PIN二极管状态的不同组合，可以将天线的工作频率调谐到7个不同的频段。该天线使用计算机仿真工具进行研究和设计，并在~ 1.0 GHz (5.05 GHz - 5.98 GHz)的频率范围内提供频率可重构性。天线的辐射特性也保持一致，在所有重新配置的频率下，平均增益为3.32 dB (3.06 dB - 3.66 dB)，百分比效率为53.05%(51.62% - 59.36%)。

A frequency reconfigurable antenna with consistent radiation characteristics

A planar frequency reconfigurable antenna is presented. The proposed antenna is derived from a rectangular microstrip patch antenna and it consists of three parasitic patches near to radiating edge of the main radiator. PIN diodes are incorporated to provide necessary electrical connectivity between the main radiator and the parasitic patches. Operating frequency of the antenna can be tuned to seven different frequency bands by setting different combinations of the PIN diodes status. The antenna is studied and designed using computer simulation tool and offers frequency reconfigurability over a frequency range of ∼ 1.0 GHz (5.05 GHz–5.98 GHz). The antenna also shows consistent radiation characteristics with an average gain of 3.32 dB (3.06 dB–3.66 dB) and percentage efficiency 53.05 % (51.62 %–59.36 %) at all the reconfigured frequencies.
