Abstract

This paper presents a compact high gain antenna for indoor communications. Here an electrically small antenna is suspended above an artificial magnetic conductor (AMC) surface to achieve a unidirectional radiation pattern within LTE 1800MHz band. The antenna is placed at the height of 0.18? above the AMC surface. The overall surface area occupied by the proposed prototype is 0.46?×0.46?. The electrically small antenna(ESA) is tested with an AMC reflector, and simulated S11response shows good agreement with the measured result. Here the proposed antenna (with AMC surface) offers fractional bandwidth of 3.3% with an average gain of 6.1dBi over the desired operating band.
