“…As presented in [20], a compact patch antenna array operating in the band of 26-31.4 GHz is able to provide ±42° beam coverage via beam switching. A dual-polarized mm-Wave antenna array operating in the band of 24.4-29.5 GHz with a scanning angle from −34° to 33° was proposed in [21]. Though these designs achieve certain promising performance, the scanning angle still needs to be extended in practical applications.…”

This paper presents a compact dual-band and dual-polarized millimeter-wave patch antenna array with satisfactory performance on element mutual coupling and beam scanning capabilities. Using capacitive feed technique and stacked configuration with extra parasitic strips, the proposed antenna array is able to achieve a wide operating bandwidth in both the low-and high-bands. In order to reduce the array's footprint, and to enhance the beam scanning performance in both bands, the element spacing is shrunk to less than 0.36 wavelength at 26 GHz. To improve the isolation between array elements due to their small spacings, two effective decoupling approaches are adopted, which result in a 6-dB isolation enhancement. The overall size of the proposed antenna array is only 18.2 mm × 4.1 mm × 1.07 mm, which is smaller than some industrial mm-Wave antenna modules released recently. Our simulation shows that the antenna array can fully cover the 5G NR bands of n258~n261 simultaneously. The four-element array provides ±60° and ±45° beam scanning performance in the low-and high-bands, respectively. The experimental data of reflection coefficient, mutual coupling, and radiation patterns confirm with the simulated results, rendering the proposed array to be a good candidate for 5G mm-Wave communications.INDEX TERMS 5G, dual-band, dual-polarization, mm-Wave, mobile phone antennas, microstrip antenna, phased array.

“…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.

“…Antenna array concepts established for 5G operation in microwave-frequency bands use several types of elements, such as a planar dipole [10,11], patch [12,13] and Vivaldi [14,15] structures, substrate integrated waveguide (SIW) [16][17][18], and slotted [19] and horn (including various ridges) [20][21][22][23] waveguides. The elements based on the planar dipole, patch and Vivaldi structures, and SIW are easy to manufacture and integrate with other planar microwave circuits; however, they may exhibit higher losses since their metallic structures are supported by a dielectric substrate.…”

Shared-Aperture 24–28 GHz Waveguide Antenna Array

A compact three-element shared-aperture waveguide antenna array for the 24–28 GHz microwave-frequency band is presented as a proof-of-concept of an array with steerable directional beam suitable for 5G telecommunication systems. The array is intended for use in a microwave photonic link and is sufficiently steerable only with the progressively phased excitation signals of equal magnitudes. The mutual interactions between the array elements are minimized to maintain the properties of the individual elements, even if they are embedded and closely spaced in the array. The proposed concept could be simply extended by adding more elements to further increase the directivity and enhance the steering properties of the array.
