Abstract :
This paper presents the study and design of a 5.2 GHz WLAN body-wearable electronically steerable parasitic antenna radiator (ESPAR) array. A collinear array of four driven dipoles and eight parasitic dipoles is formed to attain beam steering in the azimuth plane and a narrow beam in the elevation plane. The collinear ESPAR array provides beam steering in three directions while allowing 12.8 dBi of peak gain at 5.2 GHz. PIN diode switches are used to control the beam of the array.
