Small-Clearance Phased Array Antenna Design with

Abstract

In this paper, highly miniaturized radiation elements organized in a linear phased array form is introduced for fifth generation cellular communications. The design structure is composed of eight low-profile folded-dipole in the x-y plane located at the top portion of the printed circuit board (PCB) with Rogers RT5880 substrate. The radiation elements of the design are etched on the same layer of the ground plane. The proposed array is highly compact which occupies only 0.5 mm (clearance) of the PCB plane. The critical properties of the introduced phased array are investigated. The designed antenna exhibits wide beamsteering, high efficiencies, and sufficient gain levels at 28 GHz, the main 5G band. In addition, the proposed phased array design has sufficient radiation behavior in the adjacency of user-hand phantom.

Dual-Band MIMO Antenna Design for 5G Smartphones Mobile Communications

“…Presently, the 5th generation of cellular phone communication (5G) of the band is recognized as dual frequency bands in 3.42 -3.77 GHz and 5.30 -5.63 GHz. It is possible to obtain a total bandwidth of 700 MHz [11][12][13][14]. Multiple-input multiple-output (MIMO) techniques can then ominously progress the range operation and channel capabilities in communication systems without boosting transmit power and adding extra transmission bandwidth.…”
