3D Radar Localization via Photonic Chirp Leaky-Wave Antenna Beam Scanning
Steeg, Matthias; Tebart, Jonas; Neophytou, Kyriakos; Antoniades, Marco A.; Iezekiel, Stavros; Stöhr, Andreas (2019)We report a photonic frequency-modulated continuous wave (FMCW) radar system that provides 3D localization with a simple radar frontend. This is achieved by exploiting linearly polarized leaky-wave antennas (LWAs) for ...

Compact Fixed-Beam Leaky-Wave Antenna for 5G Millimeter-Wave Applications
Neophytou, Kyriakos; Steeg, Matthias; Stöhr, Andreas; Antoniades, Marco A. (2019)A planar, compact, fixed-beam leaky-wave antenna operating at 26 GHz is proposed, that consists of a periodic arrangement of series-fed microstrip patches. The antenna consists of two oppositely-directed branches of the ...

DC voltage boosting technique in radio frequency wireless power transfer systems utilising high PAPR digital modulations
Neophytou, Kyriakos; Antoniades, Marco A. (2019)This work investigates the performance of an envelope detector under high peak-to-average power ratio (PAPR) waveform excitations. First, the use of multi-stage rectifiers is investigated in wireless power transfer systems, ...

Design of PCB leaky-wave antennas for Wide angle beam steering
Neophytou, Kyriakos; Iezekiel, Stavros; Steeg, Matthias; Stöhr, Andreas (2018)A PCB based leaky-wave antenna (LWA) design for wide angle beam steering is presented. This design employs longitudinal slots inserted into a substrate-integrated waveguide for operation in the mm-wave V-band. It is optimized ...

A Geometrically Phase-Compensated Transformation Optics Superstrate for Fixed-Beam Broadband Leaky-Wave Radiation
Markley, Loïc; Noor, Asif Al; Neophytou, Kyriakos; Antoniades, Marco A. (2019)We present a broadband leaky-wave antenna designed using phase-compensated transformation optics. A graded dielectric superstrate is placed above a leaky slot line to produce radiation at a fixed angle off broadside. ...
