Microstrip Tunable Bandpass Filter with the Colinear Resonators [PDF]
International Journal of Antennas and Propagation, 2013 This paper presents the lumped element circuit and transmission line equivalent circuit for a varactor-tuned bandpass filter. The filter consists of transmission lines, fixed capacitors, and a varactor diode. The colinear resonant sections, in this filter, are not configured in parallel, as they are in a conventional combline filter.

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.Enhancing antenna gain remains a key requirement in modern wireless systems, particularly with the rapid evolution of 5G, emerging 6G networks, satellite links, and high‐resolution radar. Recent research trends increasingly rely on frequency‐selective surfaces (FSSs) and metasurface‐based reflectors, which offer precise electromagnetic wave control ...

A New Ultracompact Narrow Bandpass Microstrip Filter Using Double-Negative Quasiplanar Cells
International Journal of Antennas and Propagation, 2020 This paper presents a novel ultracompact narrow bandpass filter with high selectivity. The proposed filter is composed of cascading two basic cells. Each cell is basically a microstrip line loaded with a quasiplanar resonator and series gaps which can be

Conformal Filtering Patch Antenna With Dual Independently Tunable Radiation Nulls
International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.A conformal, compact, and flexible patch filtering antenna with independently tunable radiation nulls is presented. By etching open‐ended split‐ring resonator (SRR) slots and meandered slots on a conformal microstrip patch, two independently controllable radiation nulls are introduced to enhance band‐edge selectivity.

A Compact Wideband HTS Duplexer Using Dual‐Mode Resonators with Improved Isolation
International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.A wideband high‐temperature superconducting (HTS) duplexer is designed and is characteristic of more than 50% fraction bandwidth in its two channels. The duplexer is composed of a linear half‐wavelength resonator and two channels. Each channel is composed of five dual‐mode resonators with the attenuated second harmonic.
