Conformal Asymmetric Meandered Flare (AMF) Antenna for Body-Worn Applications

A conformal body-worn antenna is presented for communications at 300 MHz. The antenna consists of a thin broadband flared-dipole element printed on a thin (0.1 mm) FR4 substrate without metallic backing or other shielding. The letter presents the design approach for tuning, matching, and mounting the antenna on the human body. Measurements are given for a human body phantom, and these are compared to simulations. Different antenna positions for improved coverage are also presented.
