Abstract

A magneto-electric dipole antenna with high front to back ratio (FBR) for femtocell base station is proposed. By using circular defects in the ground plane, the back radiation of the antenna is reduced. The prototype antenna achieves high FBR without affecting the bandwidth and gain. At S11 = -10 dB, the simulated and measured impedance bandwidths of the proposed antenna are 58.06% (1.54-2.8 GHz) and 60.9% (1.55-2.91 GHz), respectively. The measured FBR value ranges from 21 to 29 dB. Stable unidirectional radiation pattern at both planes and average gain of 7 dBi are also obtained.
