A novel low-profile high-gain antenna based on artificial magnetic conductor for LTE applications

This paper presents a novel low-profile and high-gain antenna which adopts an artificial magnetic conductor (AMC) ground plane as its reflecting surface. Here, the traditional printed dipole antenna is oriented horizontally over the AMC surface which is consisted of 5*7 square plum-shaped patches unit without vertical via to the ground. The optimized antenna has a height about 9.5mm and its peak gain is closed to 9.7dB at 2.58GHz. Moreover, the operating frequency range is from 2.47GHz to 2.77GHz, its relative bandwidth achieves about 11.63%.
