Abstract

A novel substrate integrated waveguide (SIW) cavity-backed antenna using quarter mode SIW is proposed in this paper. The quarter mode SIW antenna is realized by splitting the SIW cavity into four parts along the fictitious quasi-magnetic wall, which can preserve the field distribution of original SIW. A leaky wave radiation can be obtained from the dielectric aperture of the fictitious quasi-magnetic wall. The proposed antenna not only has the advantages of conventional SIW cavity-backed antennas including low profile, light weight, high front-to back ratio, and easy integration with planar circuits, but also has the advantages of miniaturization and simple structure. To validate the concept, the antenna is fabricated and measured. The measurement results match with the simulation results very well.
