Abstract This study presents two novel topologies of a 2 × 2 filtering antenna subarray based on all resonator structures. The coupling matrix theory is used to extract the interresonator coupling coefficients and quality factors. The matrix paramet

This article presents a Ka-band fourth-order slotted spherical resonator waveguide bandpass filter (BPF) with a wide spurious suppression stopband. It uses the first higher-order TM211 mode rather than the fundamental TM101 mode of the spherical reso

In this paper, a third-order waveguide bandpass filter (BPF) based on slotted spherical resonators with a wide spurious-free stopband is presented. The resonator consists of a spherical cavity with slots opened at the top and bottom. Compared with a

This article presents a comprehensive active ${N}\,\,+ 4$ coupling matrix approach for the design of integrated filter–amplifier. The feedback between gate and drain, which is neglected in a previous work, is considered, which improves the accuracy
