A low-profile wideband dual-polarized microstrip antenna is presented for 5G communication. Using a periodical diamond structure, both low profile and wideband performance have been achieved with high port isolation. Relative bandwidths of 53.4% and 54.0% are obtained for two polarizations with a low profile of 0.047λ 0 , where λ 0 is the free space wavelength at the center frequency of 4.18 GHz. The dual aperture coupling method is adopted for each polarization direction and high-order modes are stimulated across the passband. The measured port isolation of more than 30 dB is obtained. Unidirectional radiation patterns have been achieved with low cross-polarization levels. The proposed dual-polarized microstrip antenna can offer a low-profile structure and wideband performance, which can be another potential candidate for the 5G communication.

This paper demonstrates a broadband dual-polarized metasurface antenna with high isolation and low cross-polarization using characteristic mode analysis. A wideband metasurface with stable radiation pattern is presented by splitting the edge patches into 2 Â 2 sub-array and introducing Minkowski fractal structure in the corner patches. To achieve the dual-polarized operation, a pair of degenerate modes of the metasurface are selected, and thus high isolation and low cross-polarization are obtained. The metasurface is excited by two slot antennas placed orthogonally. A prototype with an overall size of 1.46 λ 0 Â 1.46 λ 0 Â 0.07 λ 0 (λ 0 is the free-space wavelength at center frequency) is fabricated. The proposed antenna could achieve dual-polarization operation. The experiment results show that the À10 dB impedance bandwidths for each port are 28.9% (4.74-6.34 GHz) and 31.4% (4.62-6.34 GHz), respectively. The isolation between the two ports is higher than 31.8 dB, and cross-polarization level is better than À28 dB. Moreover, broadside radiation performances for two ports are obtained.

“…Several methods were proposed to realize a dually polarized LWA (DP-LWA), such as the dual-mode transmission line [38], symmetrical spoof surface plasmon polariton lines [39], back-to-back slot array [40], OMT based LWA [35], partially reflected surface (PRS) LWA [41], metamaterial LWA [42], and lens LWA [43]. However, all those methodologies can only provide a single beam operation for each polarization which makes them unsuitable for multibeam operations, which are essential in 5G new radio (NR) [44].…”

In this work, the concept of high-order space harmonics (HSHs) applied to a hybrid form of nonradiative dielectric (NRD) waveguide and substrate-integrated square waveguide (SIW) involving both TE10 and TE01 modes is investigated with aim to develop multi-functional dually polarized leaky-wave antennas (DP-LWAs). A polarization-selective coupling (PSC) mechanism is used to guide the two orthogonally oriented modes in the hybrid structure to achieve a polarization diversity feature. The polarization effect on unit-cell geometrical structures is examined for different characteristics of LWA such as propagation constant behavior, leakage ratio, and scanning range variation. In addition, we demonstrate how the extrinsic characteristics of HSHs in a one-dimensional periodic LWA and its unit-cell analysis can provide design flexibility through two case studies. In the first case of demonstration, we show a dually polarized multi-beam LWA design with wide scanning capability in which we use both even and odd HSHs of n ϵ [-1, -2]). The second antenna design case is concerned with a DP-LWA having the capability of fixed and scanning beams operation by using a combinatory set of PSC and four HSHs of n ϵ [-1, -2, -3, -4]. Two DP-LWA prototypes are demonstrated as proofs of concept, and the obtained experimental results show a very good agreement with their simulation and analysis counterparts.INDEX TERMS One-dimensional periodic leaky-wave antenna (1D-periodic LWA), Higher-order space harmonics (HSHs), Polarization-selective coupler (PSC), Nonradiative dielectric (NRD) waveguide, Substrate integrated waveguide (SIW), Dually polarized antenna (DPA).
