PLANAR LEAKY WAVE ANTENNA ARRAYS FOR MILLIMETER WAVE APPLICATIONS
Planar leaky-wave antenna arrays are attractive as high efficient and low cost antennas for millimeter-wave applications, for example, in radio communication and radar devices. In this article, planar leaky-wave antenna arrays composed of a printed periodic metal strip grating on a grounded dielectric waveguide and using various feeding technique for the dielectric waveguide are considered. Antenna design examples and their radiation characteristics are presented
