“…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).

“…Periodic surfaces that support dual or circular polarization are currently demanded for many practical applications such as polarimetric radar or satellite communications [1]- [3]. For this purpose, the scatterer's shape must allow strong interaction with both TE and TM-polarized incident plane waves, and thus, it must be electrically long both in x and y dimensions [4].…”

International audienceA circuit model approach is here presented to characterize bi-dimensional arrangements of dual-polarized elements. This contribution is an extension of the physical insightful approach previously proposed by some of the authors. The main novelty here resides in the fact that the scatterer may support two different current profiles. This feature becomes crucial for the accurate characterization of multiple current practical scenarios, such as the analysis and design of dual-polarized frequency selective surfaces. In particular, we illustrate its applicability when, due to oblique incidence, both an even and an odd current profiles are excited in a crossed-slot element. © 2016 European Association of Antennas and Propagation
