Low‐loss compact diplexer based on complementary spiral resonators

Microwave and Optical Technology Letters, Volume 66, Issue 6, June 2024.
Abstract The article describes a novel low‐loss microwave diplexer based on compact planar filtering elements. These are composed of spiral resonators and etched directly onto the signal layer. Furthermore, their design and optimization prove to be easy, and their native high‐pass/low‐pass characteristics are perfectly suited for assembling a diplexer.

Wideband Diplexer With Narrow Channel Spacing Using Hybrid Bandpass-Bandstop Structures

IEEE Access, 2020
In this paper, a wideband diplexer with narrow channel spacing is designed by using hybrid bandpass-bandstop structures. Two wideband bandpass structures are designed with the transmission zeros at the upper or lower passband edges to achieve high skirt ...

Frequency selective surface with a bistable auxetic geometry

Electronics Letters, Volume 60, Issue 12, June 2024.
Two bistable auxetic array geometries have been considered as FSS arrays of conducting elements. A square base form auxetic array with a combination of vertical and horizontal IT‐poles and a triangular one with three legged elements. Both of these have exhibited FSS reflection and transmission band characteristics with close band ratios.

Surface Air‐Pressure Measurements From Space Using Differential Absorption Radar on the Right Wing of the 60 GHz Oxygen Band

Earth and Space Science, Volume 11, Issue 4, April 2024.
Abstract Surface air pressure is one of the most important parameters used in Numerical Weather Prediction (NWP) models. Although it has been measured using weather stations on the ground for many decades, the numbers of measurements are sparse and concentrated on land. Few measurements from buoys and ships are available over ocean. Global measurements

Coupled Resonator Diplexer without External Junctions

Journal of Electromagnetic Analysis and Applications, 2011
A coupled resonator diplexer has been designed, fabricated, and tested. The design is based on synthesis of coupling matrix of a 3-port coupled resonator circuit using optimization. Unlike conventional diplexers, the presented diplexer configuration does not include any separate junctions for distribution of energy. The diplexer has been implemented at

Miniaturised high‐isolation K‐/Ka‐band diplexer with 3D antarafacial channel integration using vertical quasi‐coaxial matching network

IET Microwaves, Antennas &Propagation, Volume 18, Issue 4, Page 291-296, April 2024.
A miniaturised high‐isolation K‐/Ka‐band diplexer with exceeding adjacent channels using 3D antarafacial channel integration and vertical‐quasi‐coaxial‐based matching network is proposed. Working principle, design method and test solution of this proposed K‐/Ka‐band diplexer are well illustrated, and the high‐isolation (>40 dB) in very adjacent ...

Resonant-grid quasioptical diplexer

Electronics Letters, 1973
Measurements on a polarisation independent-resonant-grid diplexer are described. The grid transmits the 13·5 to 19 GHz band (loss < 1 dB). It reflects the 23 to 36 GHz band (loss < 1 dB) at an angle of 40° to the incident beam. Peak rejections exceed 44dB. Crosspolarised components are below 30dB.
