Design of EBG antenna with multi-sources excitation for high directivity applications

Abstract : In this paper, an electromagnetic band gap (EBG) resonator antenna with multi-sources excitation is proposed. The objective is to broaden the radiation bandwidth and the directivity of the EBG antenna. The directivity is increased by 13dB using EBG resonator compared to the conventional patch antenna case; a value of 20dB is obtained. The multi-sources excitation was considered to moderate the problem of the low radiation bandwidth of the antenna. By means of the multi-source excitation device (16 patches are used to effect excitation of the EBG resonator), the directivity is increased by by 1.38% compared to that the mono-source excitation, and the lateral lobes were reduced by 5dB. © 2018 The Authors.
