A Flexible Design Cross‐Coupled SIW Bandpass Filter With Different Path Loads Using Mixed‐Coupling Topology

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
This paper presents an innovative coupling design for a bandpass substrate integrated waveguide (SIW) filter, enabling high selectivity and facilitating flexible design. The proposed filter design has two parts: one is a mixed coupling structure, and the second part is a cross‐coupling path.

Design and Implementation of a New 4 × 4 BFN Using Multi‐Aperture and Multislot Coupler for 5G Application

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
This paper proposes a 4 × 4 beamforming network (BFN) using a novel configuration. The proposed architecture utilizes a two‐layer multi‐aperture and multislot coupler (MA/MSC). Power coupling between ports within each layer is achieved through designed apertures.

AGORA: Adaptive Generation of Orthogonal Rational Approximations for Frequency‐Response Data

International Journal of Circuit Theory and Applications, Volume 53, Issue 10, Page 5751-5759, October 2025.
This paper introduces the adaptive generation of orthogonal rational approximations (AGORA) method for rational function approximation of measured or simulated microwave network parameters. AGORA allows estimating the model order for a given error tolerance and does not require any initial estimates or adjustment of hyperparameters. ABSTRACT This paper
