Wearable antenna for military attire

This paper proposes a design of a dual-band button antenna with miniaturised structure. The button antenna is designed and simulated at Industrial Scientific Medical (ISM) band resonant frequency of 2.45 GHz and 5.8 GHz to be used with military garments epaulettes. The material and parameters of structure have been chosen and calculated so that the antenna is radiating with omnidirectional radiation pattern. The simulated gains of the antenna are 3.97 dBi and 7.52 dBi for the two resonating frequencies, respectively. The front to back ratio (f/b) for both frequencies are higher than 10 dB. The maximum beams are directed at 510 and 1080 respectively for E-plane, and 290 and 590 respectively for H-plane. The simulations have been performed by using Computer Simulation Technology (CST) software.
