?????????????????? ?????????????? ??????????!?? We are pleased to share with you the following featured work published on IEEE AWPL: Yingqi Zhang;?Artem R. Vilenskiy;?Vladimir I. Litun;?Marianna V. Ivashina, “A W-Band Quasi-Optical Array Antenna Feeding Network With High Taper Efficiency Using Optimal Ridge Excitation of an H-Plane Sectoral Waveguide,”????????? ???????????????? ?????? ???????????????? ?????????????????????? ??????????????,?vol. 23, no. 9, 2024. ?? ?????? ????????????????????: ·?We developed a novel H-plane quasi-optical (QO) feeding network for linear (sub-)array gap waveguide antennas at W-band (85–105 GHz), achieving an impressive 97% amplitude taper efficiency and a low insertion loss of less than 0.4 dB. ·?Our approach involves optimized input stepped-ridge excitation of the multi-modal H-plane sectoral GWG and its transition to an overmoded rectangular groove gap waveguide. This unique design ensures nearly uniform field distribution across a 20-element array, with the desired tapered phase for ?-bit beam-steering scenarios. ·?We introduced an eigenmode-based semi-analytic method that identifies the desired modal content and predicts the optimal ridge length. The results obtained with this method closely match full-wave simulations, simplifying the design process and improving understanding. ???????? ?????? ???????? ?????????? ?????????? ?????? ?????????????????? ????????: https://lnkd.in/gUuJnsNQ

The EM modal/mode-matching analysis is still fascinating (to me at least). It reveals so much happening inside waveguiding structures, hidden in the FEM/FDTD approaches.

This paper presents a promising design concept for #reconfigurable #intelligent #surfaces (#RISs), named plug-in RIS, wherein the RIS is plugged into an appropriate position in the environment, adjusted once according to the location of both base station and blocked region, and operates with fixed beams to enhance the system performance. The plug-in RIS is a novel system design, streamlining RIS-assisted #millimeter-#wave (#mmWave) communication without requiring decoupling two parts of the end-to-end channel, traditional control signal transmission, and online RIS configuration. In plug-in RIS-aided transmission, the transmitter efficiently activates specific regions of the divided large RIS by employing hybrid beamforming techniques, each with predetermined phase adjustments tailored to reflect signals to desired user locations. This user-centric approach enhances connectivity and overall user experience by dynamically illuminating the targeted user based on location. By introducing plug-in RIS’s theoretical framework, design principles, and performance evaluation, the authors demonstrate its potential to revolutionize mmWave communications for the limited #channel #state #information (#CSI) scenarios. ---- Mahmoud Raeisi, Ibrahim Yildirim, Mehmet Cagri Ilter, Majid Gerami, Ertugrul Basar More details can be found at this link: https://lnkd.in/eHPvu_qC
