Population‐based multiobjective metaheuristics are potential in microwave component designs because all electric properties could be optimized simultaneously to find several tradeoff designs in a single run. However, they often suffer extremely‐expensive computational time caused by too many full‐time objective function evaluations. In this paper, firstly, an efficient parallel implementation of MOEA/D (multiobjective evolutionary algorithm based on decomposition) is proposed to reduce the overall computational time. Secondly, optimization speed, approximation performance to the entire Pareto front, and algorithm robustness of the proposed parallel MOEA/D are investigated through extensive standard test instances. Then, a complete design procedure based on the proposed optimization algorithm is presented to locate multiple Pareto optimal designs of antenna. Finally, a compact broadband dual‐polarized antenna operating at 3.3‐5.0 GHz is designed for 5G base station applications. Comparisons are made to verify the great performance of the proposed method.

“…In reality, base-station and microcell antennas are mostly fabricated with 3D construction because it can yield both wide bandwidth and high gain easily [8]- [11]. Recently, several microstrip antennas with 3D construction have been proposed for base-station and microcell applications [12], [13]. In [12], the 3D antenna units and its corresponding feeding network are printed on substrates and arranged in a loop array, resulting with a high gain of 10.3±0.9 dBi and a low gain variation within 1.25 dB in the horizontal plane.…”

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.
