The honors thesis presented in this document describes an extension to an electrical engineering capstone project whose scope is to develop the receiver electronics for an RF interrogator. The RF interrogator functions by detecting the change in resonant frequency of (i.e, frequency of maximum backscatter from) a target resulting from an environmental input. The general idea of this honors project was to design three frequency selective surfaces that would act as surrogate backscattering or reflecting targets that each contains a distinct frequency response. Using 3-D electromagnetic simulation software, three surrogate targets exhibiting bandpass frequency responses at distinct frequencies were designed and presented in this thesis.

This thesis is done as an extension of the development of an electrical engineering capstone project. The goal of the capstone is to create a system that can receive a 2.4 GHz Wi-Fi signal out to a range of 300 meters and then use it to point in the direction of a given Wi-Fi source. The design process of the capstone system is described in depth and the results of the proposed design are presented. The thesis work explores how this system can achieve a dual band capability at both 2.4 GHz and 5 GHz Wi-Fi bands. So, a slotted patch antenna system with a slotted ground plane was designed and tested and proved to deliver the ideal characteristics for accurate signal tracking.
