Abstract

The invention discloses a scissors fork type automatic unfolding and folding antenna and a design and construction method thereof. The antenna comprises an unfolding and folding mechanism, a supporting truss, a vibrator assembly and a line concentration assembly. The scissors fork type automatic unfolding and folding antenna disclosed by the invention eliminates the defects that the existing vehicle-mounted and shipborne antennas are time-consuming and labor-consuming to unfold and fold and require more personnel, does not need to be manually disassembled and assembled, is rapid to unfold andfold, requires fewer operators, is small in size after being folded, and is easy to store and transport. The antenna can be applied to the field of communication antennas, and is especially applied tooccasions with high requirements for antenna occupation, weight, unfolding and folding, and technicians, such as vehicles, ships, airplanes, and the like. The design and construction method disclosedby the invention is simple in principle, feasible in technology and convenient to apply, technicians in the field can easily master and implement the method, the problem of rapid unfolding and folding of the antenna can be effectively solved, and the antenna is convenient and rapid.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted logarithmic period and fishbone antennas in short-wave antennas, and particularly relates to a scissors-fork type automatic unfolding and retracting antenna and its design and construction method in this field. Background technique [0002] With the increasing demand for mobile communications, the requirements for the ease of use of the structure of vehicle-mounted, ship-mounted, and airborne antennas are also increasing. At present, commonly used vehicle-mounted antennas are mainly installed and disassembled manually. Vehicle-mounted log-periodic antennas often use tube and rod structures as antenna supports, and wires as antenna surfaces. This type of antenna structure is time-consuming and laborious to disassemble. In addition, the installation and erection time requirements for mobile antennas are getting shorter and shorter. Users hope to quickly complete the antenna erection with one button, a...
