摘要

本文设计了一款应用于认知无线电的频率可重构紧凑型平面天线。基于集成了滤波器的宽带天线,利用PIN二极管实现了天线宽带和窄带工作模式的切换,通过变容二极管实现了天线窄带工作模式下频率的连续可调。宽带模式下,天线工作在2.4GHz-5GHz,此时具有良好的带外抑制效果;窄带模式下,天线的频率可调范围达1.12GHz,可调百分比带宽达28%。
In this paper, a compact frequency reconfigurable antenna applied to cognitive radio(CR) is proposed. Based on the filtenna, a PIN diode is utilized to obtain the antenna with the ability to switch the state between wideband and narrowband states. Moreover, two varactor diodes are employed to enable the antenna to continuously shift its narrowband operational frequencies. In wideband state, antenna operates in the range of 2.4 GHz to 5 GHz with excellent out-of-band rejection characteristic. In narrowband state, the frequency-agile range of it reaches 1.12 GHz, i.e., its frequency-agile fractional bandwidth 28% is obtained.
