Abstract

This paper described the design of a compact printed monopole antenna with U-shaped Defected Ground Structure (DGS) for ultrawideband (UWB) application. The implementation of DGS facilitates in reduction of size and increases in antenna performance. The DGS and antenna design parameters are simulated using CST Microwave Studio 2020, and the measurement is carried out using R&S Vector Network Analyzer (VNA). The optimized design of the proposed UWB antenna with U-shaped DGS presented smaller in size (23.88mm x 29.10mm x 0.813mm) with a reduction of 32% compared to the conventional design, which fabricated on Rogers RO4003C substrate with a relative permittivity, εr = 3.38. Simulation results show that the proposed antenna provided a very wide range of frequency (3.2 - 20GHz), 144.8% of BW. The simulated and measurement results show good agreement.
