摘要

A broadband electrically steerable parasitic array radiator (ESPAR) antenna is presented.The proposed broadband ESPAR antenna consists of an active monopole, 12parasitic sleeve wires, 6 parasitic elements and a ground structure. By introducing thesleeve wires into the ESPAR antenna, the operation bandwidth of the ESPAR antennais broadened effectively. Six copper wires placed around the circular ground planeconstitute the ground skirt of the ESPAR antenna. The ground skirt, with low windresistance, reduces the elevation angle of the radiation beam. A broadband ESPARantenna operating at 2.2 GHz is designed and fabricated. From the results, the impedancebandwidth, with a 2 VSWR, can operate from 1.70 to 2.70 GHz, which is widerthan a conventional ESPAR antenna. The working band of the proposed ESPARantenna covers the GSM1800/1900/UMTS, LTE2300/2500, and 2.4G-WLAN bands.The electronic beam steering across a range from 0° to 360° with a step size of 608 isrealized and the gain from 6.15 to 7.37 dBi is obtained over the operation band.
