Journal of Electrical and Computer Engineering, 2019 In modern microwave telecommunication systems, especially in low phase noise oscillators, there is a need for resonators with low insertion losses and high Q-factor. More specifically, it is of high interest to design resonators with high group delay. In

A Wideband Diplexer for Ka-Band Passive Intermodulation Measurement [PDF]
, 2018 In this paper we propose a novel Ka-band waveguide diplexer for passive intermodulation (PIM) measurements. Due to the higher operating frequency, this type of measurement setup usually requires wideband filters.

Nanophotonics, Volume 13, Issue 21, Page 3963-3983, September 2024.Abstract Plasmonic nanoantennas with suitable far‐field characteristics are of huge interest for utilization in optical wireless links, inter‐/intrachip communications, LiDARs, and photonic integrated circuits due to their exceptional modal confinement. Despite its success in shaping robust antenna design theories in radio frequency and millimeter‐wave

Low‐loss compact diplexer based on complementary spiral resonators
Microwave and Optical Technology Letters, Volume 66, Issue 6, June 2024.Abstract The article describes a novel low‐loss microwave diplexer based on compact planar filtering elements. These are composed of spiral resonators and etched directly onto the signal layer. Furthermore, their design and optimization prove to be easy, and their native high‐pass/low‐pass characteristics are perfectly suited for assembling a diplexer.
