A Compact Antenna Design for 5G Applications

Abstract

Owing to the recent advancement in wireless communications, 5G has triggered research in mm-wave frequencies all the way up to 96GHz. The future 5G communication standards are expected to provide 5-50Gbps of data rates. The requirements of 5G communications system is high gain for reducing propagation loses, large bandwidth with enhanced reliability and low latency. In this regard dual polarized antenna operating at 28/38 GHz band is designed. The antenna consists of a rectangular patch with fractals to achieve multiple resonances. A rectangular slot is etched off the radiating patch to enhance impedance bandwidth of the antenna. Antenna patch is excited by two orthogonal (vertical and horizontal) feed lines to achieve dual polarization. The antenna is compact with size of 32×20 . Simulated and measured results exhibit that the proposed antenna has two common -10dB impedance bandwidths of 2.7GHz (26.6-29.3 GHz) and 5.2GHz (35-40.2GHz) and high isolation between the ports. The designed antenna possesses unidirectional radiation patterns with gain of 13dBi and 12.5dBi at lower and upper frequency bands respectively
