Sukomal Dey,Shiban K. Koul +1 more
TL;DR: In this paper, a radio frequency microelectro-mechanical system (RF-MEMS) 5?bit phase shifter based on a distributed MEMS transmission line concept with excellent phase accuracy and good repeatability is presented.
Journal ArticleDOI
Design scheme for broadband Doherty power amplifier using broadband load combiner
TL;DR: In this article, the authors proposed a load combiner for broadband Doherty power amplifier (Doherty PA) using CREE 10 W packaged GaN high electron mobility transistor devices, which can be easily fabricated using conventional printed circuit processes.
Journal ArticleDOI
Modeling of LTCC-Ferrite Tunable Inductors and Development of an $\boldsymbol {L}$ -Band Phase Shifter
TL;DR: In this article, a tunable inductor using a low-temperature co-fired ceramic (LTCC)-ferrite tape and subsequent development of a loaded transmission line phase shifter using these inductors is presented.
Proceedings ArticleDOI
Reconfigurable Polarization Converter Printed on Single Substrate Layer Frequency Selective Surface
TL;DR: In this article, a thin reconfigurable polarization converter designed on a single substrate layer frequency selective surface to achieve linearly polarized and circularly polarized waves in state I and state II respectively is proposed.
Journal ArticleDOI
UWB Channel Characterization for Compact L-Shape Configurations for Body-Centric Positioning Applications
Richa Bharadwaj,S. Swaisaenyakorn,Clive Parini,John C. Batchelor,Shiban K. Koul,Akram Alomainy +5 more
TL;DR: In this paper, the body-centric channel parameter classification for various compact three-base station L-shape configurations utilizing only a 2D plane for installation is presented, and the results highlight the variation of the channel parameters with respect to the orientation of the base station configurations and the presence of the human subject.
