 This paper considers the performance of a square microstrip patch antenna designed from two layers of non-flexible conducting material (copper) separated by foam or other material which is deformable and having an approximate relative permittivity, εr≈ 1. The antenna can be incorporated into smart clothing for multi band reception and transmission in Body Area Networks (BANs). An empirical technique is presented for obtaining the shape of the antenna when it has been deformed due to body movement or by applying force at two adjacent edges. The reflection coefficient, radiation pattern and surface currents of the wearable antenna under consideration are analyzed under various bending conditions. It is found that H-plane bending did not significantly affect performance of the patch. The antenna can be used in multi-band body worn wireless applications. Â
