Millimeter Wave Circularly Polarized Fresnel Reflector for On-Board Radar on Rescue Helicopters

The increasing use of millimeter waves for civil radar application, e.g., for automotive or helicopter obstacle detection- requires the development of high gain and low cost antennas in compact form. With this aim, a Fresnel reflector with circular polarization over 5 GHz bandwidth (76-81 GHz) has b...
