Compact Printed Antenna With Loaded and Etched Bandstop Resonators: Applications in UWB Spectrum

Abstract

In this chapter, band stop-embedded structures using half-wavelength circular and quarter wavelength straight open-ended slots and split ring resonators are presented and discussed. Simulation and measured results of some efficient applications in the UWB spectrum reported in the literature are discussed. We started by presenting the main research studies results dealing with a systemic design of embedded slots used to inhibit interferences in the UWB spectrum with narrow band systems. Then, we presented an overview of bandstop/bandpass structures using SRRs coupled to a coplanar waveguide, loaded near the feed line, and slotted on the patch antenna. Systemic designs reported in the literature followed by the main results proving the efficiency of these structures have been presented and discussed.
