dual band slotted patch antenna for on/offbody communication

Body centric wireless communication (bcwc) has been topic of much research in recent years. in this manuscript, a novel lowcost microstrip patch antenna is designed for on/offbody communication with a dualband operation. the proposed structure exhibits a monopolelike 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 dualmode antenna presented. the proposed lowcost 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.
