Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] See figure 1 The first preferred embodiment of the present invention provides an array antenna 100. The array antenna 100 is used to receive input signals and radiate the received input signals in the form of electromagnetic signals. The array antenna 100 includes a cavity power splitter 10 and a final stage power split coupling radiating unit 20 installed on the cavity power splitter 10. The cavity power divider 10 is used to re...

Abstract

Provided is an array antenna, comprising a cavity power divider and a final stage power dividing, coupling and radiating unit. The cavity power divider conducts power dividing after receiving input signals to output first power dividing signals; the final stage power dividing, coupling and radiating unit comprises a dielectric substrate, a first metal surface layer and a second metal surface layer; a coupling gap array is formed on the second metal surface layer to receive the first power dividing signals; a radiating gap array corresponding to the coupling gap array is formed on the first metal surface layer; the dielectric substrate is provided with a plurality of metalized through hole units vertically passing through the first and second metal surface layers; the range corresponding to each metalized through hole unit surrounds a coupling gap and a radiating gap corresponding to the coupling gap for conducting final stage power dividing on the first power dividing signals, so as to output second power dividing signals to the radiating gap array so that the radiating gap array can radiate out the second power dividing signals. The present invention increases bandwidth.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to an array antenna. Background technique [0002] Antenna is one of the most important front-end passive components of communication equipment. Antennas play a very important role in the performance of communication products. At present, the existing slot array antenna uses rows of through holes on its surface to form the side walls of the rectangular waveguide, thereby realizing the function of the traditional rectangular waveguide. However, such antennas are serially fed. Due to the limitation of serial feeding, the bandwidth of the antenna is inversely proportional to the number of slots in each waveguide. Therefore, the bandwidth of such an antenna is relatively narrow and cannot meet the requirements of a system with relatively wide bandwidth requirements. Summary of the invention [0003] An array antenna is provided to increase the bandwidth of the antenna to meet the need...
