A CPW-fed 5.8 GHz Wideband Antenna Applied on the Human Body

Influence of the human body on a 5.8GHz wideband antenna is reported in this paper. Limited to 30X30 mm2 area on a PCBoard with ?r = 4.4, proposed antenna has two U-shaped, two F-shaped and two L-shaped slots as additional resonators to achieve wide-band operation. Measured-10 dB bandwidth is 2.68GHz (5.63 GHz~8.31 GHz). When the antenna applied to wireless body area network (WBAN) application, the characteristic of proposed antenna had been degraded to near to the-10 dB return loss. The performance of the designed antenna on body was characterized through simulations using the Finite Element Method and Method of Moment.
