Advanced RF Technologies

The Advanced RF Technologies (ART) Group is led by Prof. Psychogiou and is based at University College Cork (https://www.ucc.ie/en/) and Tyndall National Institute (https://www.tyndall.ie/) in the beautiful city of Cork, Ireland. Our research is on the intersection of electromagnetic analysis, RF circuit design, high-frequency integration methods and RF characterization techniques for RF passive and active components (filters, power dividers/combiners, phase shifters, matching networks, gain stages), antenna elements and RF co-designed front-end chains.  For more than a decade, we have been developing RF components for wireless communication transceivers, radar and space communication systems as well as for RF instrumentation. We examine novel RF design concepts and integration techniques that facilitate architectures with highly-miniaturized volume, multiple levels of transfer function adaptivity and combined RF signal processing actions. Furthermore, we investigate low-cost, hybrid integration/manufacturing schemes that enable the realization of tunable RF components for frequencies as low as 10s of MHz (UHF band) to as high as 100 GHz (W-band). We give a particular emphasis on novel RF filter synthesis techniques that allow us to create single- and multi-band high-quality factor filters (Q> 1,000) with multiple levels of RF tuning namely center frequency, bandwidth, transfer function, all within the volume of a single RF components. We specialize on RF designs that include 3D waveguide transmission lines, acoustic-wave resonators, planar and single-/multi-layer lumped-element resonators.
