A Building Block Assembly Dualband Dual-Polarized Antenna With Dual Wide Beamwidths for 5G Microcell Applications

Abstract

A dualband dual-polarized antenna element with dual wide beamwidths for 5G microcell applications is initially proposed and investigated in this paper. To achieve very low manufacturing cost, an unprecedented method is applied to the antenna element, in which the antenna components are printed separately on F-4B substrates, follow by assembling them to form the antenna element (similar to building block assembly). To further achieve high gain, an 1×4 antenna array is also designed. Measured results show that the half power beamwidths (HPBWs) in Hand E-planes are 112±1 • and 105±3 • in the lower frequency band of 3.22-3.88 GHz, respectively, and 99±3 • and 106±4 • in the upper frequency band of 4.52-5.02 GHz, respectively. In addition, high front-to-back ratio (FBR) of approximately 19 dB and high isolation of 33.6 dB can also be achieved.

A compact wide beamwidth dual‐polarized antenna for 5G new radio

“…With the continuous updating and development of 5G technology, higher requirements are put forward for antennas. In order to achieve higher data transmission rate, lower network delay, longer distance communication and wider coverage, the dual‐polarized antennas with wide beamwidth and wide operating frequency band are easier to meet the requirements for 5G, and the antennas with the characteristic of miniaturization is more convenient to be applied in practical engineering 1–3 …”

[1][2][3] Wide beamwidth antenna has been widely used in the global positioning system (GPS), radar system, and mobile communication because it has the characteristic of wide beam coverage. [4][5][6][7] At present, many researches have been done on broadening the beamwidth of antenna.…”

“…A dual‐polarized magnetoelectric dipole antenna employing a notched wall is presented in the study by Yin and Zhang 16 to improve the beam‐width of the pattern. The short wall and four fences are applied to realize the wide beam characteristics in Feng et al 17 The driven and parasitic patches are designed based on binary code to realize wide beam‐width on the dual‐polarization antenna 18 .

Dualband Microstrip Elliptic Patch 1x4 MIMO Antenna Design for 5G System Device

“…Because of its advantages such as low fabrication cost, high production efficiency, and high manufacturing accuracy, etc., since its invention, the microstrip antenna (printed on the substrate) is widely used today. However, most of the microstrip antennas are planar structures and cannot be applied in three-dimensional (3D) construction [7].…”
