Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and a low profile foam substrate with thickness of 2.5 mm are considered for the dual-mode antenna presented. The proposed low-cost structure is fabricated and the stability of its performance under the human body effects is investigated through both simulation and measurement. The experimental results are in good agreement with the simulated ones.
