Abstract

The invention discloses a planar slot antenna based on a triangular substrate integrated waveguide resonant cavity, which is fed by a coplanar waveguide on the lower surface of a dielectric plate by slotting in the edge region of the upper surface of an equilateral triangular substrate integrated waveguide resonant cavity. electricity, so that the antenna works in model. A rectangular slit is opened on the edge of the equilateral triangular substrate integrated waveguide resonant cavity, and made parallel to one side of the equilateral triangular substrate integrated waveguide resonant cavity, so that a displacement current will be generated on the slit, and electromagnetic waves will be radiated. The antenna retains the advantages of better radiation performance of the traditional cavity-backed slot antenna. At the same time, the entire antenna, including the radiation structure, feed structure and back cavity, is completely fabricated on a single-layer dielectric board, which greatly reduces the processing complexity and reduces the processing time. The cost also makes planar circuit integration easier.

Description

technical field [0001] The invention relates to a planar slot antenna based on a triangular substrate integrated waveguide resonant cavity, which belongs to the field of microwave technology. Background technique [0002] With the rapid development and application of modern communication technology, higher requirements are put forward for the miniaturization, integration and high performance of the communication system. The antenna is a very important part of the communication system, and its performance will directly affect the performance of the entire system. [0003] Traditional cavity-backed slot antennas have the disadvantages of large volume, complex structure, and high cost. Therefore, it is necessary to design a low-profile, high-gain slot antenna that is light in weight, low in cost, and easy to integrate with planar circuits. Contents of the invention [0004] In order to reduce the volume of the antenna, reduce the processing cost, and improve the radiation ef...
