Abstract

The invention discloses a slot array antenna based on a substrate integrated waveguide and a power dividing network thereof. The slot array antenna comprises a substrate integrated waveguide front surface, comprising a plurality of substrate integrated waveguides arranged in sequence and a slot array arranged on the substrate integrated waveguide; A power dividing network unit located behind the substrate integrated waveguide front; The output end of the power dividing network is connected with each substrate integrated waveguide to feed the substrate integrated waveguide; and a sum-differencenetwork unit located behind the power division network unit; The sum-difference network unit includes a sum-difference network operating in the W band, and the sum-difference network is connected with the power dividing network. According to the invention, the power dividing network unit and the sum-difference network unit are of a layered three-dimensional structure, requirements for the compactstructure,miniaturization and low profile of the antenna are realized. Moreover, the slot array antenna of the present invention works in the W band, has high frequency, can realize narrow beam and low sidelobe, and can provide extremely high precision and good resolution.

Description

technical field [0001] The present application belongs to the technical field of antennas, and in particular relates to a slot array antenna based on a substrate integrated waveguide and a power division network applied to the slot array antenna. Background technique [0002] Antennas are an important part of wireless communication systems. With the progress of society and the development of technology, the demand for high performance and miniaturization of electronic systems is becoming increasingly urgent. Array antennas are widely used in electronic systems in many fields such as communication, navigation, radar, and detection, and can achieve high performance. The miniaturized array antenna structure will inevitably bring good economic and social benefits. [0003] Substrate Integrated Waveguide (SIW) is a new type of waveguide structure that can be integrated into a dielectric substrate. This structure arranges multiple metallized through holes at a certain interval in ...
