Design of High Gain Wearable Rectangular Microstrip Textile Antenna for Wireless Application

Abstract

Wireless body area networks have paying more attention in the recent decade. The microstrip textile antenna used for wireless applications (ISM Band) such as emergency rescue, health monitoring and medical care. In this paper, the square patch microstrip textile antenna is introduced which is mounted on the flexible jeans substrate. The physical size of the suggested/simulated textile antenna is 52.99 X 45.23 mm2 & the jean’s material is used as substrate with its relative permittivity of ɛr = 1.67. The proposed antenna is radiating at the center frequency of 2.45 GHz with a return loss of -15.76 dB & VSWR 1.389, the far field directivity of an antenna is 8.05 dBi at 2.45GHz. The designed antenna is wearable on the clothes because the use of textile material for antenna fabrication by keeping SAR at 1.6 W/Kg.
