Novel Compact Quad‐Band HMSIW BPF and FPD With Low Loss and Tunable Passbands

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
This work introduces a new quad‐band bandpass filter (BPF) and filtering power divider (FPD) based on half‐mode substrate integrated waveguide (HMSIW) technology and metamaterial concept. To achieve a high level of miniaturization, multiple design approaches are jointly employed, including HMSIW implementation, evanescent‐mode operation, stepped ...

Microwave Diplexer Purely Based on Direct Synchronous and Asynchronous Coupling [PDF]

Radioengineering, 2016
A diplexer realized purely based on direct coupling is presented. No cross-coupling is involved in the design process. The microwave diplexer is achieved by coupling a dual-band bandpass filter onto two individual channel filters.

Wideband Millimeter‐Wave Balun‐Diplexer Based on a Novel Coupled Marchand Architecture for Compact Footprint and Phased‐Array Integration

Microwave and Optical Technology Letters, Volume 67, Issue 11, November 2025.
ABSTRACT This letter presents the first reported wideband balun‐diplexer for mm‐wave applications, designed for shared‐aperture full‐duplex array systems. By integrating balun and diplexer functionalities in a single component, we enable per‐element self‐interference suppression, while also facilitating the interface between the balanced feed of the ...

Design Procedure for Interdigital Waveguide Bandpass Filters Based on Flat Metallic Strips

Radio Science, Volume 60, Issue 3, March 2025.
Abstract In this work, we describe a new topology for interdigital bandpass filters implemented in waveguide technology. Compared to classical coaxial resonators, which are typically based on cylindrical metallic posts, the resonators that we propose are based on rectangular boxed cavities loaded with flat metallic strips of a finite thickness.
