Abstract

The invention discloses a double-H slot coupling-based self-detection microstrip antenna array. The double-H slot coupling-based self-detection microstrip antenna array comprises at least seven layersof structures, wherein the structures are microstrip antenna units, a first dielectric plate, an antenna ground plate with double H slots, a second dielectric plate, a strip line layer which is provided with a coupling line, a third dielectric plate and a strip line ground plate which are sequentially arranged from top to bottom; the strip line layer and the second dielectric plate form a feedingnetwork; the double H slots in the antenna ground plate couple fed radio frequency energy to the microstrip antenna units; the coupling line transmits the vertically-polarized energy of each microstrip antenna unit to an output port by means of spatial coupling of electromagnetic fields in the second dielectric plate and the third dielectric plate; and the energy is compared with previously stored coupled energy data, so that whether the microstrip antenna units fail can be judged. According to the double-H slot coupling-based self-detection microstrip antenna array of the invention, the self-detection of the antenna array is realized through a coupling network. The antenna array has the advantages of low design complexity, high recognition efficiency of fault antenna units and the like.

Description

Technical field [0001] The invention belongs to the technical field of microwave antennas, and relates to a self-detecting microstrip antenna array based on double H slot coupling. Background technique [0002] During the development of a project, based on the anti-jamming requirements of the project, the antenna is required to achieve horizontal and vertical dual polarization functions. At the same time, considering that the product needs to be stored for a long time, the antenna should be inspected before each use to accurately identify the faulty antenna unit in the antenna array. For this reason, the antenna needs to increase the coupling self-check function. Therefore, it is necessary to design an antenna array that can simultaneously realize the dual-line polarization function and the self-detection function. Through literature search, many patent documents and non-patent documents describe the design method of slot-coupled microstrip antenna. [0003] In the design of the...
