Embodiment Construction

[0071] The embodiment of the present application provides a method and device for determining the slotting method of the antenna patch, which is used to expand the bandwidth of the antenna by slotting the patch, and at the same time restrict the target resonant frequency of the antenna, and limit the resonant frequency of the antenna. at the target resonant frequency.

[0072] The technical principle of the embodiment of this application can be described as: grooves are made on the surface of the patch, which changes the original current flow direction of the patch, makes the current flow direction tortuous, and thus makes the current path longer, and finally affects the equivalent circuit of the antenna, which is equivalent to The addition of cascaded inductors is equivalent to increasing the electrical length of the antenna, which is a very effective way to widen the bandwidth of the antenna. Through the technical solution provided by the embodiment of the present applicatio...

Abstract

The application discloses a method and a device for determining the slotting mode of an antenna patch, in order to constrain the target resonant frequency of an antenna and limit the resonant frequency of the antenna at the target resonant frequency while extending the bandwidth of the antenna through patch slotting. The method for determining the slotting mode of an antenna patch provided by theapplication includes the following steps: for each preset slotting mode of an antenna patch, determining the fitness corresponding to the slotting mode according to the target resonant frequency of anantenna and the actual resonant frequency and reflection coefficient of the antenna corresponding to the slotting mode; and determining the slotting position of the antenna patch according to the fitness corresponding to the multiple slotting modes.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for determining a slotting manner of an antenna patch. Background technique [0002] With the rapid development of the mobile Internet, microwave spectrum resources are increasingly scarce, and the future 5G system will expand to the millimeter wave frequency band. Antennas are an important part of wireless communication systems, and the research on antennas in the corresponding millimeter-wave frequency band has become one of the hotspots. Microstrip antennas have the following advantages: simple two-dimensional physical structure, relatively low cost of manufacturing and designing microstrip antennas. Compared with the single microstrip patch antenna, the patch antenna array can provide higher gain at a little extra cost, and the matching and phase adjustment can be adjusted by printing the microstrip feed structure, by the same method ...
