Abstract
A compact, low-profile pattern-reconfigurable antenna working at 2.4GHz is presented in this paper. The antenna exhibits two symmetrical switchable tilted beams with the maximum radiations at around ±60° off the z-axis in elevation plane. In contrast to omnidirectional antennas, directional antennas that can change their beam direction according to the location of sensors are beneficial in terms of energy consumption, signal sensitivity and long communication range. The proposed antenna can be used for on-body communication in some cases beam tilts are desired, for example the paths in the belt-to-wrist. The characteristics of antenna in free space and placed above a simplified human tissue are analyzed.
