Design of Dual-Band Printed-Dipole Array Antenna with Omni-directional Radiation Behaviour

Abstract

In this paper, we present a compact array of 4 printed dipole antennas with ground plane, operating at 2.7 GHz and 5.2 GHz, designed for base station applications. First, the elementary printed dipole antenna, selected for its small size and good performances, is described. However, this kind of structures cannot cover two bands at the same time, which justify our proposal of a 4-elements network. Next, the 4-elements array is simulated, optimized, and measured to proof its performances with good agreement between the measurements and simulations. The measured gain of the 4-dipoles array is 4.21 dBi and 6.15 dBi for both operating frequencies 2.7 GHz and 5.2 GHz, respectively.
