“…In [7], a broadband coverage of 27-29 GHz is achieved by three well designed slot arrays. In [8], the proposed beam controllable collinear dipole array can operate from 22 GHz to 34 GHz. In [9], a mm-Wave magnetoelectric monopole antenna with vertically polarized end fire radiation is presented, which achieves both low profile and broadband coverage of 23.5-44 GHz characteristics.…”

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.

“…While microstrip antennas have been the subject of many intensive works for decades [20][21][22][23][24], they have been considered in some research efforts reported in the past few years on antenna design aspect of the newly emerging mmW wireless communications [19,[25][26][27][28][29][30][31][32]. Antennas in [19] and [25][26][27][28] are mainly designed to operate in one of the target frequency bands, as listed in Table 1.…”

“…The element has a wide bandwidth of 13 GHz, centered at 31.5 GHz, but the maximum achievable gain is only 5.3 dBi. In [30], Samsung Telecommunications proposed a 4-element beam steering capable dipole array with a bandwidth of 12 GHz, centered at 28 GHz, with a moderate maximum gain of 7 dBi. In [31], a four-element dense dielectric (DD) patch array antenna was introduced in which electromagnetic bandgap (EBG) structure and a dielectric superstrate were used to improve the radiation characteristics.…”

Abstract-Wideband arrays have recently received considerable attention in 5G applications to cover larger frequency bands. This paper presents a novel design of a high gain and wideband antenna subarray from 23 GHz to 32 GHz, which covers the frequency bands proposed by the Federal Communications Commission (FCC) for 5G communications. The proposed subarray consists of four radiating elements with wideband and high gain characteristics. These elements are composed of two stacked patches, which are fed using the proximity coupling technique. A unit-cell element prototype is first fabricated and tested to validate the gain and bandwidth performances. A 1 × 4 subarray prototype is then fabricated and tested, while maintaining an element spacing less than half-wavelength at the center frequency, to avoid grating lobes and to keep the small size of the antenna subarray. The measurement results of the prototypes, i.e., unit cell element and subarray prototypes, show good agreements with the simulations. The subarray measurements demonstrate a high gain of 10-12 dBi, an impedance bandwidth of 33.4%, and a 1-dB gain bandwidth of 10.5%. The proposed antenna subarray is a good candidate for wideband and high gain antenna arrays suitable for 5G mmW applications.
