The Journal of Engineering, Volume 2019, Issue 19, Page 5877-5879, October 2019., 2019 In this study, a novel high‐isolation wideband divider based on multi‐layer elliptical defected ground structure coupler is presented along with its analytical theory and design procedure. The proposed divider could be conveniently applied for high‐ power applications with less loss for the absence of isolation resistors.

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 ...
