Matthias Steeg, a PhD student from the University of Duisburg-Essen (UDE, Germany) has recently visited the lab of Stavros Iezekiel, in the University of Cyprus ( UCY, Latsia, Cyprus) during 29 days, with the aim of developing and fabricating a 5G 26 GHz photonic beam steering transmitter. Therefore, PCB leaky-wave antennas, produced at UCY during the STSM, are integrated with microwave photodiodes from UDE to enable changing the beam direction of the transmitter remotely through photonic techniques employing tunable lasers.
