Problems solved by technology

The above reasons directly determine that the processing cost of the traditional rectangular metal waveguide antenna is relatively expensive, and it is difficult to directly realize the gapless integration between the antenna and the system
Although the microstrip antenna is light in weight and small in size, it is susceptible to external interference and has unwanted back radiation, so it is necessary to design a suitable antenna to meet the needs of the communication system

Embodiment Construction

[0019] A substrate-integrated waveguide dual-frequency broadband slot array antenna unit for a communication system, comprising a dielectric substrate 1 covered with metal patches 2 and 3 on both sides, and a substrate-integrated waveguide 4 is arranged on the dielectric substrate 1, One end of the substrate integrated waveguide 4 is short-circuited. Grooves 51, 52 and tuning metallized through holes 61, 62 are respectively provided in the substrate integrated waveguide 4 and on both sides of the center line. The above substrate integrated waveguide 4 is composed of two rows of metal Metallized through-holes 71 and 72 are formed, and the short circuit at one end of the substrate integrated waveguide 4 is closed by the metallized through-hole 8 . The above-mentioned metallized through hole is to open a through hole on the dielectric substrate, set a metal sleeve 9 on the wall of the through hole and connect the metal sleeve with the metal patches covering both sides of the diele...

Abstract

This invention discloses one chip integration waveguide double frequency wide band gap array antenna unit used in communication system, which comprises medium chip with both sides coated with metal paster, wherein, the chip is located with chip integration waveguide with one end shortcut and the both sides of the center line are separately located with groove and tuning metal hole and the waveguide is composed of two rows of meal hole with another end shortcut sealed by metal hole.

Description

technical field [0001] The invention relates to an antenna used in a communication system, in particular to a substrate-integrated waveguide dual-frequency broadband slot array antenna unit. Background technique [0002] Microwave and millimeter wave antennas have been widely used in modern communication systems. As an essential part of the communication system, the modern communication system puts forward high requirements on the microwave and millimeter wave antennas. First of all, it should have a wide operating bandwidth, high gain and good directivity; secondly, the antenna can be easily integrated into other system circuits; thirdly, the antenna should be small in size, light in weight, and low in processing cost. low enough to be used in large-scale commercial production. In addition, in some specific communication systems, there are specific requirements for antennas. For example, in a communication system working in FDD mode, the antenna is required to work indep...
