“…Over the past many years, the former type is widely researched. The latter type is also worthy of studying, which is indispensable components as push‐pull amplifiers, 2 antennas, 3‐5 and mixers 6 in the modern communication circuit design. Therefore, greater efforts have been taken into achieving the out‐of‐phase feature such as double‐sided parallel strip lines (DSPSLs), 7 modified Gysel PDs (GPDS), 8 multilayer substrate integrated waveguide (SIW), 9 asymmetrical coplanar strip lines (ACPSs) 10 and microstrip‐to‐slotline transitions 11 …”

In this article, a feasible design of an ultra‐wideband power divider (PD) based on spoof surface plasmon polariton (SSPP) is proposed. A quasi T‐junction transmission structure is composed of the sub‐wavelength corrugated grooves drilled on the up metal layer, realizing the wideband and low loss for the propagation of the odd‐mode SSPP wave. The consistency of the dispersion curves between the H‐shaped and the U‐shaped unit cells under the same dimension parameters ensures the smooth transition at the bifurcation point and out‐of‐phase property further. The odd‐mode SSPP is effectively excited by using the microstrip‐to‐slotline convertor. Some design details like gradient corrugations and stepped slotlines are employed to achieve high‐coupling efficiency from the input electromagnetic energy. The simulated and measured results show that the proposed PD achieves 180° ± 5° phase difference over an ultra‐wideband from 3.3 to 9.8 GHz (a relative bandwidth of 99.24%) with high‐transmission efficiency. The ultra‐wideband out‐of‐phase property of this design has potential applications in the differential feed network.

“…Thus, they are not useful for an imaging application, where scanning rate (defined as the rate of change of main beam direction θ with respect to frequency) is preferred as high as possible [28]. In order to achieve a high scanning rate, a slow wave structure appears an effective way, and some designs have been proposed in [28]- [31]. Ref.…”

A class of 45 • linearly polarized and circular polarized high scanning rate leaky wave antennas are proposed in this paper, which is based on slow-wave substrate integrated waveguide structure. High scanning rate leaky wave antennas have recently become attractive for imaging applications and automotive radar. These applications also require a continuous scanning range without an open stopband, as seen at broadside for ordinary leaky wave antennas. Furthermore, both 45 • linearly polarization and circularly polarization are required in practical applications. In this paper, we propose an all-in-one leaky wave antenna design, which features high scanning rate, continuous scanning capability across the broadside, 45 • linear polarization or circularly polarization, single-layer configuration, and single-side radiation. Two design examples are provided to illustrate the proposed principle. Both simulation and experimental validation are given.

In this article, a substrate integrated waveguide (SIW) antenna utilizing odd‐mode spoof surface plasmon polariton (SSPP) for broadside radiation is proposed. Double gratings are etched on the top surface of SIW and the SSPP odd‐mode is excited on this hybrid SIW‐SSPP structure. The proposed SIW antenna has open‐circuit termination and can realize broadside radiation. A prototype of the SIW‐based odd‐mode antenna is fabricated. Reasonable accordance is achieved between measured results and simulated results. The antenna impedance bandwidth is about 5.5% (12.4~13.1 GHz) with |S11| < −10 dB. Stable broadside radiation is also realized within the operating band of 12.3~13.3 GHz and the measured gain varies from 5.66 to 6.34 dB in the frequency band. The proposed broadside radiation antenna is suitable for wireless communication systems due to its compact structure and good radiation performances.
