Abstract: A pattern reconfigurable antenna array for 5.8 GHz wireless body area network (WBAN) applications is proposed in this paper. The antenna array consists of a radiation component and a controller component. The radiation component comprises four planar F-shaped antennas, which are located on the four corners of the upper layer and are rotated 90° anticlockwise from each other. The controller component is located in the lower layer and includes a four-port controllable network. An omnidirectional radiation pattern tangent to the human body surface and a directional radiation pattern normal to the human body surface can be obtained by controlling the PIN diodes, which are integrated in this controllable network. Measurements of impedance bandwidth, radiation pattern, and gain are performed when the array is mounted on the human body or forearm phantom, and the results agree with the simulation. Specific absorption rate (SAR) values for both radiation modes, and beam switch ability are also simulated to ensure the practicability of this array.
