Design of triple-layer double U-slot patch antenna for wireless applications

Abstract

Many techniques have been proposed to design microstrip patch antennas with multiband characteristics. In the proposed antenna design, acombination of dual U-slot and multiple layers is used to get multiple bands and wide bandwidth. A multiband triple-layer probe fed double U-slotmicrostrip patch antenna for next generation wireless applications is proposed in this paper. Parametric studies of antenna structure with doubleU-slot, variation of feed position, and also with multiple layers are presented. The proposed antenna is fabricated and tested. The simulation andexperimental results are presented. The proposed antenna provides triple bands at 1.6 GHz, 1.9 GHz and 3.8 GHz and a bandwidth of 600 MHz fora substrate thickness of 1.6 mm and 1.8 GHz, 2.2 GHz and 4.8 GHz and a bandwidth of 800 MHz for a substrate of 0.6 mm thickness.All Rights Reserved © 2015 Universidad Nacional Autónoma de México, Centro de Ciencias Aplicadas y Desarrollo Tecnológico.
