This paper introduces the research of applications of metamaterial-based antennas recently developed in our lab. They include the planar antennas with multi-band multi-function operation, high gain property and enhanced beam scanning ability.
In this paper, planar beam scanning substrate integrated waveguide (SIW) slot leaky-wave antennas (LWAs) are proposed for gain enhancement using a metallic phase correction grating cover. Unlike conventional Fabry-Pérot (FP) cavity antennas, the proposed antenna is fed by the SIW beam scanning LWA instead of a feeding antenna. The beam scanning angle range is enlarged by meandering the entire feeding...
