Investigation of an Array of Dipoles in Three-Dimensional Configuration

In this paper, an array of printed dipole antenna organised in a three-dimensional (3D) configuration is investigated. The dipole is printed on a low-cost FR4 substrate, with each arm on either side, and fed by a parallel transmission line. The dipole resonates at 3.5 GHz. The dipole is organised on a 2 x 2 x 2 configuration. The array elements are fed to achieve maximum beam at the front or broadside and achieves a gain of 10.40 dBi in this direction. Beam scanning over the entire 360° is possible with this 3D configuration for both E and H plane. In this work the gain is fairly consistent throughout the 360° scanning with a variation of only 2.2dB in E-plane and 3.2dB in H-plane. This configuration looks promising for 5G and future communication system.
