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.

Three‐Way Equal Filtering Power Divider for Modern Communication Systems
Engineering Reports, Volume 7, Issue 1, January 2025.A balanced three‐way filtering power divider that receives input power and delivers equal amount of output to its three output ports is developed and realized using microstrip technology. The design is well‐suited for modern communication systems due to its low insertion and return losses, sharp selectivity, and integrated filtering capability ...

Electronics Letters, Volume 61, Issue 1, January/December 2025.A miniaturized suppressing cell (MSC) as a lowpass filter (LPF) is introduced using interdigital shaped resonator to apply in harmonic controlled power amplifiers (PAs.) The cut‐off frequency locates at 2.21 GHz. A sharp transition region (0.6 GHz) is concluded from −3 to −40 dB. Since harmonic control circuits (HCCs) are important blocks in the design
