摘要

本研究介绍了一种紧凑型频率可重新配置共面波导（CPW）馈电超宽带（UWB）天线的设计和实验验证，该天线能够按需拒绝 5.15 GHz 至 5.85 GHz 范围内的 WLAN 频率，特别适合微波成像应用。本文介绍并讨论了设计和实验结果。通过在天线的馈线和地平面之间使用 T 形槽来增强带宽，并通过在天线背面使用开环谐振器（OLR）来抑制 WLAN 波段。使用一个 PIN 二极管和一个偏置电路在有 WLAN 带缺口和无 WLAN 带缺口的 UWB 模式之间进行切换。仿真结果与实验数据完全吻合，并清楚地显示了用于微波成像应用的有趣的频率可重构行为。针对乳腺肿瘤检测提出了一个天线性能仿真和分析模型，发现两种工作模式的天线都具有肿瘤效应。

Compact CPW-fed Antenna with Controllable WLAN Band-rejection for Microwave Imaging

This work presents the design and experimental validation of a compact frequency reconfigurable coplanar waveguide (CPW)-fed ultra-wideband (UWB) antenna with a capability to on-demand reject WLAN frequencies within the range of 5.15 GHz to 5.85 GHz, specifically tailored for applications in microwave imaging. The design and experimental results are presented and discussed. The bandwidth enhancement is obtained by using T-shaped slots between the feedline and the ground plane of the antenna, and the WLAN band is rejected by using an open loop resonator (OLR) placed on the antenna backside. Switching between UWB with and without WLAN band-notched modes is performed using a PIN diode and a bias circuit. The simulation results corroborate well with the experimental data and clearly showed an interesting frequency reconfigurable behavior for use in microwave imaging applications. An antenna performance simulation and analysis model is presented for breast tumor detection, and the tumor effect has been noticed for both operating modes of the antenna.
