Abstract
A novel hybrid high impedance surface is presented and a beam steerable four feed square loop antenna is built on this structure. At a test frequency of 4.7GHz, the proposed hybrid high impedance surface based square loop antenna is 4.69mm high and has an impedance bandwidth of 650MHz and directivity of 8.7 dBi. Compared with the earlier reported steerable square loop antenna the new antenna's performance equates to a thickness reduction of 61, bandwidth enhancement of 150, a directivity improvement of 2dBi, a co-polar sidelobe reduction of 11dB, and a cross-polarisation sidelobe reduction of 5dB. © The Institution of Engineering and Technology 2009.
