[IEEE 2019 International Conference on Electromagnetics in Advanced Applications (ICEAA) - Granada, Spain (2019.9.9-2019.9.13)] 2019 International Conference on Electromagnetics in Advanced Applications (ICEAA) - Design of fully-planar CSRR-based substrate integrated waveguide circuits
摘要： We present here a fully planar, low-cost and easy to fabricate power divider and a slot array antenna operating at 5G communication bands, based on a new version of the substrate integrated waveguide (SIW). The proposed SIW is synthesized by replacing each via row, with two rows of broadside-coupled complementary split ring resonators (BC-CSRRs), etched on the top and bottom metal ground surfaces of the dielectric substrate. Such resonators provide a negative effective permittivity and are capable of perfectly confining the wave within the propagating channel. The proposed waveguide exhibits excellent propagation characteristics, with losses close to those of the conventional SIW, providing a highly promising platform to implement low-cost planar components for 5G applications.

Substrate-Integrated-Waveguide Power Dividers: An Overview of the Current Technology
摘要： Power dividers are important components of microwave/millimeter wave (mm-wave) circuit design. This article provides a comprehensive review of the state-of-the-art substrate-integrated-waveguide (SIW) power dividers/combiners. SIW technology converts waveguide-like structures into planar form, compensates for the drawbacks of microstrip structures at higher-frequency circuit designs, and minimizes production complexity and costs compared to conventional waveguide structures. An overview of how traditional dividers have progressively adopted the SIW technique is presented and a comparative performance analysis of the divider types and practical paradigm show the future potential of SIW technology.

BROADBAND PLASMONIC CIRCUITRY ENABLED BY CHANNEL DOMINO SPOOF PLASMONS
摘要： Building of compact plasmonic integrated circuits based on domino spoof plasmons (DSPs) is an important requirement and still a challenge. In this work, we report the ?rst demonstration of two kinds of channel domino plasmonic circuitries, which consist of an easy-to-manufacture periodic chain of metallic box-shaped elements inside two ?nite metallic plates. We reveal that only the channel DSPs itself rather than the hybrid TE10 and DSPs modes is supported in the part of the channel domino plasmonic waveguide with or without the metallic vias on both sides. Two channel domino plasmonic ?lters based on the e?cient transition structures are designed, and the simulated S-parameters and near electric ?eld distributions show excellent transmission performance in broadband. Utilizing the lateral insensitive property of these two channel DSPs, two kinds of broadband plasmonic power dividers/combiners are ?rstly implemented. Excellent transmission performance validates our optimizations and indicates that the proposed scheme can be easily extended to other bands. This work provides a new route for construction of deep-subwavelength DSP devices in application of high integration of microwave and terahertz circuits.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Low-cost Hardware Platform for Angle of Arrival Estimation Using Compressive Sensing
摘要： Source localization using compressed sensing in indoor RF-based AoA localization has been theoretically studied in the past. These theoretical analysis has revealed that using compressive sensing techniques for small RF antenna arrays is feasible. In this paper we present a hardware architecture which implements the random projections needed for compressive sensing, implemented using 2-port and 4-port lumped Wilkinson power dividers. We introduce the hardware architecture and how the topology of the system can be altered to achieve the necessary decorrelation in the projection process. We illustrate the efficacy of our proposed approach through a source localization experiment.
