Abstract :
In this paper, we present a wearable antenna design and process using genetic algorithm (GA) optimization. The antenna platform conforms to a human shoulder and all optimization calculations are performed in the presence of the human body. The optimization focuses mostly on the vertically polarized gain pattern (in the azimuth plane) and on matching. The required operational frequency is in the range of 220MHz-370MHz (UHF band). GA optimization is used as a starting point and subsequent simplifications are made for fabrication ease.
