Abstract

The invention discloses a rotary log-periodic antenna capable of being unfolded and folded automatically. The antenna comprises a bottom turntable system; an antenna support is arranged on the turntable system; the antenna support comprises an unfolding and folding mechanism; a spiral elevator, a guide rail and a sliding block are arranged in the unfolding and folding mechanism, a pull wire rod isinstalled at the top of the unfolding and folding mechanism, roots of four shear fork type supporting trusses formed by assembling square pipes and pin shafts are installed on four side faces of theunfolding and folding mechanism respectively, the middle portions are connected with the unfolding and folding mechanism through pin shafts, and every two supporting trusses are opposite to form a cross shape. The rotary log-periodic antenna capable of being unfolded and folded automatically disclosed by the invention is simple in design method principle, feasible in technology and convenient to apply. Compared with an original antenna mode of manual disassembly and assembly, the antenna is rapid to unfold and fold, few in operation personnel, small in size after being folded and easy to storeand transport.

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,...
