Abstract

A simple, low profile and pattern reconfigurable antenna with a full-ground plane is presented for use in wireless body area networks at 5.8 GHz ISM band. The antenna consists of a probe-fed circular patch, and a parasitic ring surrounding it. The ring is loaded with a rectangular slot on each side of the patch, and two PIN diodes are added in the center of each slot. With all the diodes in on-state, the antenna presents monopole-like radiation patterns with the gain of 4.2 dBi for maximum coverage on the body, whereas the pattern of the antenna can be directed to ±15° with an increased gain of 2.9 dBi, by turning off each diode for the semi-directional patterns states. Measured results of the fabricated prototype antenna show good agreement with numerical results obtained using Ansys HFSS.
