Abstract
In this paper the design and experimental characterization of a coplanar waveguide-feed planar inverted F antenna for wearable personal communications are presented. The proposed antenna is designed to operate at GSM 1800 MHz and ISM 2450 MHz bands. Experimental measurements of the reflection coefficient are achieved by considering two scenarios: the antenna under bending conditions and when it is placed on different textile materials for weareable applications. Moreover the measured radiation patterns and peak gains are obtained in bending and no bending conditions. The results demonstrate that the reflection coefficient is maintained below − 10 dB, the bandwidth is approximately to 10%, and the radiation properties are suitable when the bend is less than or equal to 80 $$^{\circ }$$ .
