Embodiment Construction

[0038] 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.

[0039] 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.

[0040] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a log-periodic antenna, and the antenna comprises a supporting column and a supporting truss; the supporting column extends in the vertical direction, and the supporting truss comprises a plurality of truss parts; the truss parts are arranged in the circumferential direction of the supporting column, and the truss parts are symmetrically distributed relative to the supporting column. The log-periodic antenna has the advantages of being reasonable in structural layout, firm, reliable, stable in gravity center, high in safety performance, good in directivity and small in antenna size.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a logarithmic periodic antenna. Background technique [0002] The logarithmic periodic antenna is a broadband antenna with simple structure and excellent performance. It has the advantages of wide frequency band, high gain and good directivity. It has been widely used. There are many forms of log-periodic antennas. At present, the most widely used one is the log-periodic dipole antenna. [0003] However, the traditional vibrator-type logarithmic periodic antenna still has the problem that one end is large and the other end is small. Due to the unreasonable structural layout, the center of gravity of the structure is unstable or heavily biased to one end, posing safety hazards. Contents of the invention [0004] The main purpose of the present invention is to propose a log-periodic antenna, aiming at solving the technical problem of the existing log-periodic antenna that the structural ...
