Abstract

Microstrip patch antennas have been used in many applications since their appearance. Despite their great promise, their narrow bandwidth and the loss at high-frequency bands have limited their usage in medical applications. This work proposes a developed low-cost microstrip patch antenna suitable for microwave imaging (MWI) applications within the wideband frequency range. The proposed antenna is loaded with an artificial magnetic conductor (AMC) to improve the antenna performance. The simulated results obtained using computer simulation technology (CST) indicate that the presence of the AMC has improved the frequency selectivity of the antenna at 8.6 GHz with a peak realized gain of 9.90443 dBi and 10.61 dBi for simulated and measured results, respectively. The proposed microstrip antenna has been fabricated to validate the simulated results, and its performance is tested experimentally. Additionally, the fidelity factor of face-to-face (FtF) and side-by-side (SbS) scenarios have been presented. The breast phantom models with a tumor and the antenna operating as a transceiver have been numerically simulated for the application of cancer tumor cell detection. The work will have a significant impact on the design of electromagnetic biosensors.

摘要

微带贴片天线自问世以来已经在许多应用中得到了应用。尽管它们具有很大的潜力，但它们的带宽较窄，高频带的损耗限制了它们在医学应用中的使用。这项工作提出了一种开发的低成本微带贴片天线，适用于微波成像 (MWI) 应用在宽带频率范围内。所提出的天线采用人工磁导体 (AMC) 进行加载，以改善天线性能。使用计算机仿真技术 (CST) 获得的模拟结果表明，在 8.6GHz 时，AMC 的存在提高了天线的频率选择性，模拟和测量结果的峰值实现增益分别为 9.90443 dBi 和 10.61 dBi。已经制造了所提出的微带天线来验证模拟结果，并对其性能进行了实验测试。此外，还提出了面对面 (FtF) 和并排 (SbS) 情况的保真度因子。已经对具有肿瘤的乳房体模模型和作为收发器工作的天线进行了数值模拟，以用于癌症肿瘤细胞检测。这项工作将对电磁生物传感器的设计产生重大影响。
