Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a broken line type directional microstrip antenna. The antenna comprises a radiation patch, a feed probe, a short circuit pin, a dielectric plate and a metal floor; the radiation patch and the metal floor are arranged on the upper surface and the lower surface of the dielectric plate respectively; the short circuit pin penetrates through the dielectric plate to connect themetal floor and the radiation patch together; the feed probe penetrates through the dielectric plate to be connected with the radiation patch; and the radiation patch is of a broken line type structure formed by a first set of broken line segments and a second set of broken line segments. Relatively high gain and good directional diagram characteristics are realized; the antenna has a good front-to-back ratio characteristic in a working frequency band; and the antenna also has the characteristics of easiness in processing and low profile.

Description

technical field [0001] The invention relates to the field of wireless communication equipment, in particular to a zigzag directional microstrip antenna. Background technique [0002] With the continuous development and promotion of wireless communication networks, the propagation environment in which the antenna system is located has become more and more complex. Electromagnetic waves will be interfered and attenuated when propagating in free space. If the energy radiated to the surroundings can be concentrated and sent, It will enhance the anti-interference ability of the signal. In a scenario with a large user density, from the perspective of the transmitting device, since point-to-point communication is to be realized, the antenna is also required to have very good directional radiation characteristics to meet the needs of communication. [0003] However, the maximum radiation direction of the traditional microstrip antenna is in the side-fire direction, and the gain in ...
