Compact Dual-Mode Single-Band Microstrip Antenna for Body Area Network Applications

Abstract

A dual mode microstrip patch antenna operating at 2.45 GHz is presented in this article. The design and analysis of the proposed antenna with two modes that is on-body and offbody is accomplished by ANSYS HFSS Electromagnetic software. The on-body mode is obtained with the help of square-ring patch, whereas off body mode is achieved with slotted circular patch placed inside the square-ring patch. Both the patch antennas are independently fed, but share a common ground plane among them. Radiation pattern, $S -$parameter, radiation efficiency of the proposed antenna have been presented here. The antenna can be suitable for body area network applications in the industrial, scientific, and medical band(ISM).
