Abstract

The invention discloses an automatically retractable rotary logarithmic periodic antenna, which includes a bottom turntable system and an antenna support installed on the turntable system. The antenna support includes a retractable mechanism, and a spiral elevator and a guide rail are built in the retractable mechanism. and sliders, install the pull rod on the top of the retractable mechanism, and the roots of the four scissor-fork support trusses assembled by square tubes and pin shafts are respectively installed on the four sides of the retractable mechanism, and the middle part and the retractable mechanism pass through. Connected by pins, the four supporting trusses form a cross in pairs. The rotating logarithmic periodic antenna disclosed by the invention has the advantages of simple design method, feasible technology and convenient application. Compared with the original form of manually disassembled and assembled antenna, the antenna can be unfolded and folded quickly, with fewer operators, small size after folded, and easy storage and transportation.

Description

technical field [0001] The invention belongs to the field of communication antennas, in particular to an automatically unfolding and retracting rotating logarithmic periodic antenna in the field. Background technique [0002] With the increasing demand for mobile communications, the requirements for the ease of use of vehicle-mounted, ship-mounted, and airborne antenna structures are also getting higher and higher. 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. Furthermore, the installation and erection time requirements for mobile antennas are getting shorter and shorter. Users hope to quickly complete the antenna erection and use the antenna for communication in the shortest time. With the improvement of use requirements,...
