This paper presents a novel single-feed tri-band planar inverted-F antenna (PIFA). The antenna is comprised of cascading two metallic PIFAs vertically, which are fed by a common coaxial cable. Adding ...

This work presents a compact and low-cost monopulse feed antenna based on gap waveguide at W-band. The proposed antenna is based on a pyramidal horn fed by a comparater network, integrating in ...
