Design of Textile Antenna for Military Applications

In this paper design and implementation of a textile patch antenna will be discuss for military application. The antennas used for military application must be light weight and are needed to work in rough environments surroundings such as rain, heat, snow etc. The antenna design should be thin, lightweight, low cost of maintenance, easily integration into garments and its performance should not get affect by any activity of wearer. Operating frequency of antenna is 2.4 GHz which lies in ISM frequency band. Substrate material used is Jeans fabric with dielectric constant of 1.76 and thickness of substrate is 3mm. Copper is used as conducting material for ground and patch. The antenna is of compact size as compared to calculation based on frequency and dielectric constant. The antenna proposed in this paper is fabricated and results of it are analyzed which are mentioned below. Software used for designing and simulation of antenna is High-Frequency Structure Simulator (HFSS).
