Design a Reconfigurable Patch Antenna for Mobile Application

Abstract

In this paper, a modified rectangular reconfigurable

patch antenna with inset feed is analyzed and simulated for the

Modern mobile communication Applications. The proposed

antenna is simulated by applying CST Microwave Studio

software and fed through strip line feeding. The overall size of

the antenna is 48 mm × 38 mm × 1. 59 mm. The antenna has

operated on two different resonant frequency bandwidth of 2.37

GHz and 2.45GHz for lower band of Wi-Max and Bluetooth

band respectively. The simulated gain of the antenna in the

obtained frequency range is close to 2.82 dBi and 3.11 dBi for

OFF and ON respectively. Maximum radiations are directed

normal to patch geometry and shape of patterns is somewhat

similar to a dumble shape in the upper hemisphere. This

Reconfigurable Patch antenna is specifically designed for the

application of Mobile communication systems
