Problems solved by technology

[0002] The common ultra-wideband antenna loading notch technology, due to its small size, often only tries one or two notches on the antenna unit to block electromagnetic interference in related frequency bands. In addition, the common loading notch will refer to the new The branch design of the common antenna will change the size of the common antenna and affect the matching effect of the antenna. In addition, the two-element antenna designed now will interfere with each other due to the mutual coupling of the current during work.

Embodiment

[0020] refer to figure 1 , the present invention is described in further detail below in conjunction with the accompanying drawings:

[0021] A two-element broadband antenna device, comprising a substrate 100, a two-unit patch 200 is arranged on the substrate 100, and the unit patch 200 adopts a partial fractal structure, that is, two squares are iteratively arranged on one side of the antenna unit. Make two chamfers 220 on the opposite side, these practices can ensure that the antenna can work in the specified ultra-wideband frequency band (3.1-10.6GHz).

[0022] Due to the wide operating frequency band of the ultra-wideband antenna, it is prone to electromagnetic interference from other frequency bands. Therefore, in order to avoid interference from other frequency bands, a U-shaped slot 210 is arranged on the unit patch 200, and three U-shaped slots are arranged on the unit patch. , to ensure that the antenna can avoid electromagnetic interference in three frequency bands,...

Abstract

The invention discloses a binary broadband antenna device. The device comprises a substrate; two unit patches are arranged on the substrate; and U-shaped grooves used for blocking electromagnetic interference are formed in the two unit patches. The binary broadband antenna device is simple in structure; the electromagnetic interference of related frequency bands is blocked through the U-shaped grooves, and three trapped waves can be loaded through the three U-shaped grooves; and meanwhile, the problem that the size of the antenna is changed due to the introduction of new branches at present isavoided; an independent ground board structure is adopted, and ground board branches are loaded, and therefore, the isolation degree is improved; and a better isolation effect is further ensured through the orthogonal feeding of the two unit patches.

Description

technical field [0001] The invention relates to the field of broadband antennas, in particular to a two-element broadband antenna device. Background technique [0002] The common ultra-wideband antenna loading notch technology, due to its small size, often only tries one or two antenna notch on the antenna unit to block the electromagnetic interference of the relevant frequency band. In addition, the common loading notch will refer to new The branch design will change the size of common antennas and affect the matching effect of the antennas. In addition, the two-element antennas currently designed will interfere with each other during operation due to the mutual coupling of currents. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a two-element broadband antenna device, which includes a substrate, and two-unit patches are arranged on the substrate, and U-shaped grooves for blocking electromagnetic interferen...
