Problems solved by technology

[0002] Due to the development of intelligence and automation technology, short-wave antennas are now widely used in various communication fields, but short-wave antennas are relatively large in size because their wavelengths are much larger than microwave antennas, which is not suitable for carrying, even for vehicles. In addition, due to its large structural size, it has caused great difficulties in the installation of the antenna. It requires the joint efforts of multiple personnel and takes a long time to complete the assembly.

Abstract

The invention discloses an automatic foldable logarithmic periodic antenna, include antenna mounting plate, the upper and lower ends of the antenna mounting plate are respectively rotatably connectedwith a tensioning torque rod, the left side of the antenna mounting plate is connected with an expansion rod perpendicular to the left side of the antenna mounting plate, Between that top end of the telescopic rod and the out ends of the two tension torque rod, edge cables are respectively connected, a plurality of vibrators are connected between the two edge cables at intervals, and a tension cylinder is respectively connected with the bottom side of the telescopic rod and the inner ends of the two tension torque rods. By using the telescopic cylinder and the tensile cylinder together, the antenna can be automatically opened and closed, the outdoor operator is saved, the structure is compact, the portable is easy, and the antenna can be installed on the vehicle, and is suitable for the operation in the harsh environment in the field. All the parts do not need to be disassembled and assembled, and do not need any tools for the parts when the antenna is operated.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an automatically folded logarithmic period antenna. Background technique [0002] Due to the development of intelligence and automation technology, short-wave antennas are now widely used in various communication fields, but short-wave antennas are relatively large in size because their wavelengths are much larger than microwave antennas, which is not suitable for carrying, even for vehicles. In addition, due to its large structural size, it has caused great difficulties in the installation of the antenna. It requires the joint efforts of multiple personnel and takes a long time to complete the assembly. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the above-mentioned technical problems in the related art, the present invention proposes an automatically folding ...
