In this article, a double truncated circular patch (DTCP) with a defective ground structure (DGS) and having a microstrip line feed was addressed. The proposed antenna is designed to operate from 2.75 to 14 GHz (11.25 GHz spectrum). The desired antenna is printed on FR-4 substrate. A (PGP) partial ground plane with a notch was printed on the backside of the substrate to approach the ultrawideband (UWB-3.1-10.6 GHz) characteristics. The patch was truncated on the top and left sides of the circular patch to attain the characterization of UWB. The performance and characteristics of this antenna can be evaluated through reflection coefficient (S11), voltage standing wave ratio (VSWR), and radiation patterns and gain. The performance of this antenna is analyzed by using simulated results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
