Conception of a Low-Profile and High-Gain EBG Resonator Antenna with wide bandwidth

In this paper, we present the conception of a LOW-PROFILE and High-Gain EBG Resonator Antenna which is excited by several feeds. The antenna structure has been modelled with CST MICROWAVE STUDIO, an FIT (Finite Integration Technique) based software and meets the requirements of a precise specifications. It has a cut-off frequency of 1.2GHz and delivers a maximum gain of about 18 dB over a bandwidth of 59%. The size of this antenna is small in accordance with the specifications, as it is 700 mm long and wide for a very low height of 16 mm which is equivalent to λ/16.
