Abstract

This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna to achieve UWB and Single/Dual continuously tunable-notch behaviors. The Single/Dual notched was continuously tuned to our desired frequency band by changing the value of the capacitors. The antenna designed and fabricated to validate these behaviors had a compact size of 24 × 30.5 mm², including the ground plane. The radiation patterns were very clean due to the placement of the proposed resonator in the special ground plane. Moreover, the presented novel resonator and switching technique was compared with the recently proposed resonators and their switching techniques. The prototype for the antenna was also developed in order to validate its performance in wireless vital signs monitoring. The presented miniaturized resonator based antenna was utilized for tumor sensing and simulations were provided in this regard. Moreover, the deployment of the proposed resonator based UWB antenna sensor in Pipeline Integrity Monitoring system was also investigated and discussed.

摘要

本文提出了一种新颖的谐振器，它可以使用小型化电容器在同一天线内切换并产生三种重要的行为。该谐振器被集成到传统的超宽带 (UWB) 天线中，以实现 UWB 和单/双连续可调陷波行为。通过改变电容器的值，可以连续将单/双陷波调谐到我们期望的频带。为了验证这些行为，设计并制造了一个尺寸紧凑的天线，其尺寸为 24×30.5mm²，包括接地平面。由于在特殊的接地平面中放置了所提出的谐振器，因此辐射图案非常干净。此外，还将所提出的新型谐振器和切换技术与最近提出的谐振器及其切换技术进行了比较。还开发了天线的原型，以验证其在无线生命体征监测中的性能。基于所提出的小型化谐振器的天线用于肿瘤感应，并在这方面提供了模拟。此外，还研究和讨论了基于所提出的谐振器的 UWB 天线传感器在管道完整性监测系统中的部署。
