A wideband dual-polarized antenna is proposed for 4G and 5G communication applications. The antenna element consists of a pair of opened-loop dipoles for dual-polarization and its three inherent resonant modes are shifted closer to form a wide bandwidth. With additional U-shaped slots etched around the feed point, the input impedance of the antenna element is matched to 50 Ohm. The fabricated antenna element operates from 1.8 to 4.0 GHz, having 75.9% (VSWR ≤ 2) impedance bandwidth and high port-toport isolation (> 25 dB). It also achieves a 67±1 • beamwidth in H-plane and 68.7 ± 3.3 • in V-plane with 8.5 ± 1 dBi gain across the supported bands. By using six antenna elements and designing RF phase shifting module (RFPSM) based on vector modulators, a six-element dual-polarized array with electrically downtilt is also fabricated and measured, realizing a peak gain of 16.8 dBi, a similar beamwidth in H-plane as single antenna element and an electrically downtilt in V-plane from 0 • to 12 • which is preferred in communication applications. This antenna array could be used for future 5G communication and other applications. INDEX TERMS Wideband, dual-polarized, electrically downtilt, opened-loop dipoles, 5G.

A fully planar dual polarized radiating element with internal embedded coupled dipoles is presented in this paper. The inclusion of these elements allows achieving three different goals: firstly, an extension of the bandwidth towards lower frequencies (from 1.69 GHz to 1.427 GHz) as required in new 5G standards; secondly, a reduction of the antenna size in comparison with other topologies for bandwidth extension and, finally, a reduction of the secondary lobes. The proposed dual polarized broadband antenna is based on two sets of dual polarized dipoles, with a fully planar structure. The objective of this paper is the design of an antenna working in the extended 5G band in order to fulfil the future 5G requirement in the microwave region, in which the new frequency bandwidth goes from 1.427 up to 2.69 GHz with the return losses lower than −14 dB and the crosspolar isolation larger than 28 dB.

“…Various broadband dual-polarized directional antennas have been investigated. As a typical dual-polarized antenna, crossed dipole [3][4][5][6][7][8] attracts great attention and numerous relevant researches show excellent performance. Crossed dipoles which achieve great impedance matching performance is illustrated in References 3-5 but the profile of this directional cross-dipole is too high.…”

In this article, a broadband dual-polarized microstrip antenna with low profile and compact horizontal size is presented. By using the grid-slotted patch, dual modes can be excited to broaden the operating bandwidth of the proposed antenna. A broad bandwidth of 25%(1.4-1.8 GHz) for return loss >10 dB is achieved in our design. Two orthogonal linear polarization waves are excited when two pairs of aperture are utilized to couple the grid-slotted patch. Current distribution varies with frequency which results in a broad and varying beam width. Consequently, a roughly flat gain curve appears in our design. The proposed antenna achieves a low profile of 0.09 λ 0 (λ 0 is the free-space wavelength at 1.6 GHz) and a compact horizontal size. A prototype is fabricated and measured to prove the simulation.
