Dual-polarized Dual-band Mobile 5G Antenna Array

Abstract

In this paper, a dual-band dual-polarized phased antenna array for 5G mobile terminals is proposed. The array has a bandwidth of 3.6 GHz and two resonances at 30.5 and 32.8 GHz. The array has a clearance of 2.85 mm and fed with two ports in simulation to excite the notch and dipole parts of the proposed antenna structure. Finally, the proposed antenna element is combined into two arrays with different configurations. It is shown that it is better to use the array of 8 elements than to use two 4-element sub-arrays with orthogonal orientation.

Design of a Millimeter Wave Microstrip Patch Antenna using 52GHz for Mobile Communication

“…In a research conducted by Muhammad and Majeed in the paper "Millimeter-Wave Pattern Reconfigurable Antenna" used a frequency of 79GHz and still obtained a bandwidth of 1GHz. This same result was obtained by Igor, Shual and Pedersen in works titled "Dual-Polarized Dual-band Mobile 5G Antenna Array" which operated on a frequency of 33.5GHZ [12]. At end of this research I discovered that a higher bandwidth can be obtained when a frequency of 52GHz was used to design the antenna (preferably, the microstrip patch).…”
