“…As clearly shown in the table, the proposed array outperforms most of the existing solutions in terms of height profile and average size of the array element (i.e., total size/number of array elements). More importantly, [6], [7], [10]- [12] are all broadside antenna arrays. They do not provide the same coverage, nor do they face the same design challenges as endfire arrays, especially for the realization of vertically polarized radiation in very thin Compared with the quasi-endfire array reported in [19], this work can provide similar H-pol gain and higher V-pol peak gain with only half the number of elements.…”

This paper presents a very low-profile (0.105λ 0 at 28 GHz) dual-band dual-polarized millimeter-wave phased array for 5G smartphones. The array element is based on two distinct dual-band antennas to realize two orthogonal linear polarizations. A planar folded dipole with a parasitic strip is used to produce horizontally polarized radiation, and a novel hexagonal bridge antenna is devised to generate vertically polarized radiation while maintaining a very low profile. A prototype of a 1 × 4 phased array is designed and implemented on a multilayer laminate using standard printed circuit board process. The real estate of the array is kept within 6.5 mm × 23 mm × 1.12 mm. For both polarizations, the −10 dB bandwidth covers 25.4-30.84 GHz and 38-40 GHz with peak gains of 11.31 and 11.93 dBi at two center frequencies, respectively. The overlapped 3 dB scan ranges between both polarizations are ±45 • at 28 GHz and ±39 • at 39 GHz. This work considers a number of important design challenges of implementing low-cost mmWave antennas in smartphones, providing a practical solution to mmWave 5G mobile devices.

“…All the results discussed above show that the MIMO based corporate feed arrays are very suitable for future 5G millimeter wave communication. The proposed antenna can be optimized to give dual band operation in the standard 5G bands by using either the approach of double-layer gridded patches [ 41 ] or the use of overlapped apertures [ 42 ].…”

This paper presents a design of multiple input multiple output (MIMO) antenna array for 5G millimeter-wave (mm-wave) communication systems. The proposed MIMO configuration consists of a two antenna arrays combination. Each antenna array consists of four elements which are arranged in an even manner, while two arrays are then assembled with a 90-degree shift with respect to each other. The substrate used is a 0.254 mm thick Rogers RT5880 with a dielectric constant of 2.2 and loss tangent of 0.0009, correspondingly. The proposed MIMO antenna array covers the 37 GHz frequency band, dedicated for 5G millimeter-wave communication applications. The proposed antenna element yields a gain of 6.84 dB, which is enhanced up to 12.8 dB by adopting a four elements array configuration. The proposed MIMO antenna array performance metrics, such as envelope correlation coefficient (ECC) and diversity gain (DG), are observed, which are found to be under the standard threshold. More than 85% of the radiation efficiency of the proposed MIMO antenna array is observed to be within the desired operating frequency band. All the proposed designs are simulated in computer simulation technology (CST) software. Furthermore, the measurements are carried out for the proposed MIMO antenna array, where a good agreement with simulated results is observed. Thus, the proposed design can be a potential candidate for 5G millimeter-wave communication systems.

A one-time-reflection equivalent model of the full-corporate waveguide feed networks is investigated to propose a novel approach to bandwidth enhancement of millimeter-wave large-scale antenna arrays. Theoretical analysis reveals that the in-phase superposition phenomenon of multiple small reflections at specific frequencies caused by the topology of the feed network is also a significant factor to affect the achievable bandwidth of the large-scale arrays, apart from the bandwidth performance of the individual power dividers and radiators composing the array. In order to weaken the undesirable effects on bandwidths caused by the small reflections, a full-corporate waveguide feed network with an X-type topology is then presented. Air-filled waveguide X-junctions and waveguide-fed horn sub-arrays are designed to fulfill new threedimensional (3D) printed V-band antenna arrays. Excellent performance, including an improved bandwidth of about 40%, a gain of up to 27.8 dBi, and stable unidirectional radiation patterns with cross polarization of less than -32 dB, are confirmed experimentally by an 8 × 8 prototype. The theoretical model and the bandwidth enhancement scheme in this paper are valuable to realize the high-gain wideband antenna arrays for emerging millimeter-wave applications.
