Proposed geometry of broadband printed antenna with U-slot in ground plane

Broadband printed antenna with modified rectangular patch and U-slot in ground plane

Iram Nadeem, Dong-You Choi

Abstract


A broadband patch antenna is presented with a modified rectangular patch containing three symmetrical slots and an asymmetrical slot. A U-slot is inserted into the ground plane, which enables a wide operational fractional bandwidth of 143% ranging 2.9–17.5 GHz. The modified rectangular patch offers acceptable omnidirectional radiation pattern at higher frequencies with radiation efficiency of 83 to 95%. The maximum achievable gain is 5.48 dBi across the entire bandwidth. The electromagnetic wave modeling is conducted using high frequency simulator structure (HFSS) and the circuit model is simulated with Advance Designing System (ADS) software. The housing effect is studied using vertical orientation of antenna to approximate its performance in the presence of conducting bodies. The proposed antenna architecture has small electrical dimension of 0.17×0.11λ. Simple configuration and wide bandwidth makes proposed patch antenna a suitable candidate for versatile communication applications.
