A novel dual-polarization/dual-pattern stripline-fed annular-ring slot antenna for body-centric communication systems working in the IEEE 802.11a frequency band at 5.725-5.825 GHz is presented. A stripline feeding technique has been implemented in order to reduce the back radiation level and make the antenna suitable for wearable communication systems. The planar antenna has been designed to provide capabilities for implementation of a polarization/pattern diversity scheme in body-centric communications. Two prototypes have been fabricated and characterized. The design criteria is described and measurements of return loss, isolation between ports and principal plane radiation patterns and radiation efficiency are shown. A measurement campaign has been carried out to evaluate the diversity scheme performance.

Abstract
A novel dual-polarization/dual-pattern stripline-fed annular-ring slot antenna for body-centric communication systems working in the IEEE 802.11a frequency band at 5.725-5.825 GHz is presented. A stripline feeding technique has been implemented in order to reduce the back radiation level and make the antenna suitable for wearable communication systems. The planar antenna has been designed to provide capabilities for implementation of a polarization/pattern diversity scheme in body-centric communications. Two prototypes have been fabricated and characterized. The design criteria is described and measurements of return loss, isolation between ports and principal plane radiation patterns and radiation efficiency are shown. A measurement campaign has been carried out to evaluate the diversity scheme performance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
