Abstract
The invention discloses a triangle substrate-integrated waveguide resonator-based planar slot antenna. The antenna works in a mode as shown in the specification by slotting an edge region of the upper surface of an equilateral triangle substrate-integrated waveguide resonator and feeding a coplanar waveguide on the lower surface of a dielectric plate. A rectangular slot is formed in the edge of the equilateral triangle substrate-integrated waveguide resonator and is parallel to one side of the equilateral triangle substrate-integrated waveguide resonator, so that displacement current is generated on the slot; and an electromagnetic wave is radiated outside. By the antenna disclosed by the invention, the advantage of relatively good radiation property of a traditional back cavity slot antenna is reserved. Meanwhile, the overall antenna comprises a radiation structure, a feed structure and a back cavity which are completely manufactured on the single-layer dielectric plate, so that the processing complexity is greatly reduced, the processing cost is reduced and the planar circuit integration also becomes easier.
