Abstract

Embodiments of the invention disclose a feeding structure and a dual-frequency common-caliber antenna, relates to the technical field of communication, and can solve the problem of low utilization rate of the antenna caliber due to difficult realization of multi-frequency common-caliber of an antenna structure in the prior art. According to the method, the dual-frequency common-caliber antenna comprises a first feeding structure corresponding to a first frequency band, wherein the first feeding structure comprises a first dielectric substrate and first metal layers arranged at two opposite sides of the first dielectric substrate; and a second feeding structure corresponding to a second frequency band, wherein the second feeding structure comprises a second dielectric substrate, a conversion structure, and second metal layers arranged at two opposite sides of the second dielectric substrate, a signal output end of the second dielectric substrate is connected with the conversion structure, the conversion structure comprises a third dielectric substrate, a fourth dielectric substrate, and a common substrate, the third dielectric substrate is connected with the fourth dielectric substrate through the common substrate, and the first feeding structure and the second feeding structure are arranged in a crossed manner.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a feeding structure and a dual-frequency common-aperture antenna. Background technique [0002] Antenna is a component that radiates and receives electromagnetic waves in communication electronic equipment. In order to maximize the bandwidth and information transmission in the limited space of communication electronic equipment, multi-frequency common-aperture antennas are gradually used. To realize multi-frequency antenna common-aperture antenna, one of the key technologies is the design of feed structure. In recent years, the feed structure based on SIW has been widely used, which not only ensures low loss, but also makes the feed structure easy to integrate with other circuit structures. The existing feed structure based on the SIW (Substrate Integrated Waveguide, substrate integrated waveguide) structure is mainly a plate structure, that is, a 1-to-8 power-divided fee...
