Design of Dual Band Antenna with Asymmetric Microstrip-fed Dual U-shaped for Wireless Applications

Abstract

This paper presents, a novel antenna operates for wireless applications. The proposed antenna is cascaded U-shaped patch with slits is considered with asymmetric micro strip feed on patch and defected ground is proposed in the ground plane. The proposed asymmetric cascaded dual U-shaped patch antenna resonates dual bands at 1.81GHz and 3.87GHz with −41dB and −23dB reflection coefficients respectively. The proposed U-shaped antenna attains radiation patterns at the dual bands. The proposed U-shaped antenna antenna is used for IoT applications.
