Problems solved by technology

However, the inherent characteristics of the aforementioned technical solutions require more manpower and material resources to participate in the erection, withdrawal, and storage of antennas, and there are no examples of automated applications.
It leads to time-consuming, laborious and inefficient, which often delays the fighter
It still cannot meet the needs of some applications that require high mobility requirements

Embodiment Construction

[0046] The preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0047] figure 1 An ordinary log-periodic antenna shown has a size of about 3m (length)×4m (height), and is composed of an assembly line 2 and a plurality of pairs of upper and lower oscillators 3 installed perpendicular to the upper and lower sides of the assembly line 2. In order to reduce the height dimension of the antenna, all the dipoles 3 can be unloaded or loaded, for example, the load is composed of a vibrator loading section 3-1 that is horizontally and electrically continuous with the vertical part. All parts shown are conductive metal bodies, which together form a complete log-period antenna, which participates in radiating or receiving electromag...

Abstract

The invention discloses a full-automatic log periodic antenna. The full-automatic log periodic antenna is capable of meeting high mobility requirement, fixing requirement or the like application requirements. The full-automatic log periodic antenna takes full advantages of the lifting function of an antenna mast, a soft line oscillator and an automatic line winder for winding and storing the soft line oscillator to full automatically mount, wind and store antenna. The full-automatic log periodic antenna realizes to full automatically switch the antenna working states without manual operation; the full-automatic log periodic antenna is easy to highly and organically integrate with a carrying platform, the platform shape is rarely influenced, and the cross-country mobility of a carrying tool is not influenced; the full-automatic log periodic antenna can adapt to the application requirements of different special fields and greatly improve the quick response ability of the system.

Description

Technical field [0001] The present invention relates to a communication antenna, in particular to a fully automatic logarithmic period antenna which can provide fast response capability and has high mobility. Background technique [0002] The ultra-wideband characteristics of log periodic antennas make it widely used in the fields of shortwave, ultrashortwave, and microwave communications. Its main structural feature is composed of a collection line as a transmission line and a plurality of pairs of radiating oscillators installed symmetrically on the collection line. The overall size of the antenna is related to its working frequency band, and the size is larger in the axial direction of the assembly line and the axial direction of the vibrator. Generally, the maximum dimension in the axial direction of the vibrator is about half a wavelength of the lowest operating frequency of the antenna, and the dimension in the axial direction of the assembly line is about half to 1 wavele...
