Design and Analysis of Double Truncated Circular Patch for Ultrawideband Applications

Abstract

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.
