A Compact Maritime Harmonic Radar Antenna for Navigation and Search-and-Rescue Open
This paper presents a compact dual-band dual-polarized slotted waveguide array antenna designed for a maritime harmonic search-and-rescue system. The harmonic radar transmits signals in the S-band and receives clutter-free signals in the C…

Design of a Polarization Rotating SIW-Based Reflector for Polarimetric Radar Application Open
Polarimetric radar systems are beneficial for identifying and classifying targets but require multiple transmit or receive channels with different polarizations. This leads to a high hardware effort and thus higher costs. To use a single, …

Experimental demonstration of metamaterials application for mitigating scan blindness in phased array antennas Open
This paper presents two metamaterial-inspired solutions to mitigate the scan blindness effects in a phased array antenna. In the first solution, portions of a bed of nails are introduced in the radome to prevent the excitation of surface w…
