Problems solved by technology

1. Although the ordinary logarithmic periodic antenna can form high-gain directional work, its main structure is made of rigid material and its size is large, so it cannot be quickly expanded and collected.
2. Ordinary soft logarithmic periodic antenna, although it can form a high-gain directional work, its main structure is a flexible cable (soft rope), and the size is small after storage, but it cannot be equipped with a servo mechanism, and it cannot be raised and lowered with the antenna mast. And automatically expand, collect

Abstract

The invention discloses a logarithmic period antenna that can be automatically unfolded and stored, and relates to a high-gain directional vehicle-mounted or fixedly installed antenna device in the field of communication countermeasures. It consists of log-periodic antenna, electric antenna mast and other components. It uses a vibrator retractor to realize the expansion and storage of the antenna vibrator as the electric antenna mast is raised and lowered, so as to realize the automatic expansion and storage of the logarithmic period antenna. The invention has the characteristics of small storage height, simple structure, reliable performance, etc., and is especially suitable for use as a high-gain vehicle-mounted or fixed-installation antenna in the ultrashort-wave frequency band.

Description

technical field The invention relates to a logarithmic periodic antenna in the ultra-short wave frequency band in the field of communication countermeasures. The invention is especially suitable for vehicle-mounted and ground fixed communication countermeasure systems as a high-gain automatic unfolding and storing directional interference antenna device. Background technique In the field of communication countermeasures, there are several types of high-gain directional antennas that can be formed in the ultrashort wave frequency band, but they all have certain defects in performance. 1. Although the ordinary log-periodic antenna can form a high-gain directional work, its main structure is made of rigid material and its size is large, so it cannot be quickly unfolded and stored. 2. Ordinary soft logarithmic periodic antenna, although it can form a high-gain directional work, its main structure is a flexible cable (soft rope), and the size is small after storage, but it cann...
