Abstract

The invention relates to a folding and unfolding structure and method of a log-periodic antenna. The folding and unfolding structure comprises a log-periodic antenna array, and the log-periodic antenna array comprises a truss, a plurality of layers of first antennas arranged on the truss, a plurality of first connecting pieces and a first antenna folding and unfolding device, wherein each layer offirst antenna comprises a pair of first oscillators, the pair of first oscillators are connected to the two sides of the truss respectively, each first oscillator comprises a first fixed section anda first movable section movably connected with the first fixed section, and the end, away from the first movable section, of the first fixed section is connected with the truss; two ends of each firstconnecting piece are respectively connected with the first movable sections of two adjacent first oscillators in the extending direction of the truss; the first antenna folding and unfolding device is installed on the truss and connected with the first movable sections on the two sides of the truss, and the first antenna folding and unfolding device is used for unfolding and folding the first antenna. And the log-periodic antenna array can be folded, so the occupied area is reduced, and the problem of transportation difficulty caused by overlong oscillators is solved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a deployment structure and a deployment method of a logarithmic periodic antenna. Background technique [0002] Due to the characteristics of long propagation distance, low cost and strong anti-interference ability, coupled with the ease of operation and flexibility of the equipment, the short-wave antenna has an irreplaceable unique position in the field of military and civilian communications. Among them, the short-wave antenna in the short-wave antenna is widely used due to the advantages of wide frequency bandwidth and good directivity. However, when the transmission frequency of the short-wave antenna is required to be 3-30Mhz, the corresponding logarithmic period antenna oscillator length is about 25m, that is, the use of 3 wires The structural form of the antenna is also about 15 meters in length, which is a big challenge for the current vehicle-mounted tra...
