Continuously Frequency‐Tunable Horn Filtennas Based on Dual‐Post Resonators
International Journal of Antennas and Propagation, Volume 2019, Issue 1, 2019., 2019 This work reports the concept and development of two mechanically frequency‐tunable horn filtennas for microwave and millimeter‐waves. Our design approach relies on the integration of a horn antenna with a mechanically tunable filter based on dual‐post resonators.

The Journal of Engineering, Volume 2018, Issue 4, Page 242-247, April 2018., 2018 In this study, a periodic structure as a passband filter for differential input signals is introduced that suppresses the common‐mode noise with a high common‐mode rejection ratio on a wide range of frequencies. The unit cell of the periodic structure consists of open‐ended stubs under common‐mode and short‐ended stubs under differential‐mode ...

Advanced Engineering Materials, Volume 27, Issue 15, August 2025.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Design of a Novel Ultrawide Stopband Lowpass Filter Using a DMS‐DGS Technique for Radar Applications
International Journal of Microwave Science and Technology, Volume 2015, Issue 1, 2015., 2015 A novel wide stopband (WSB) low pass filter based on combination of defected ground structure (DGS), defected microstrip structure (DMS), and compensated microstrip capacitors is proposed. Their excellent defected characteristics are verified through simulation and measurements.
