Embodiment Construction
[0018] Such as figure 1 Shown, be the working state form of portable composite material short-wave whip antenna of the present invention, i.e. the basic form of the present invention, it is made of root end cover 1, inboard bistable composite material tube 2, outside bistable composite material tube 3, Copper wire 4, locking hoop 5, top end cover 6, fixed rope 7, fixed nail 8 constitute.
[0019] The inner bistable composite material tube 2 and the outer bistable composite material tube 3 are cured and molded with 2 layers of plain weave glass fiber composite material prepreg, and the vacuum bag forming process is adopted. The included angle is 45°. After solidification and molding, the inner bistable composite material tube 2 and the outer bistable composite material tube 3 are stretched with a section angle of 300° and a thickness of 0.6 mm.
[0020] The principle of the inner bistable composite tube 2 and the outer bistable composite tube 3 is as follows: the composite ope...

A portable composite material short-wave whip antenna device is composed of bistable composite material tube, copper wire, root end cover, top end cover, fixed rope and fixed nail. The invention introduces the bistable composite material tube as the support structure of the whip antenna, and pre-embeds the copper wire into the composite material tube. During transportation, the copper wire and the bistable composite material tube are curled and stored stably without additional structural constraints. The weight of the whip antenna device is reduced, and the volume during transportation is reduced. When in use, unfold the bistable composite material tube in the curled state, insert the openings of the two bistable composite material tubes into each other, and install the root end cap and the top end cover, one end of the copper wire is in contact with the prefabricated feeder interface on the root end cover, the end cover is locked with the bistable composite material tube with a locking hoop, the fixed rope is tied to the top end cover, and the bistable composite tube is erected The material pipe adopts fixing nails to fix the root end cap and the fixing rope respectively. The invention has the advantages of small device weight, small transportation volume, convenient carrying, simple erection, etc., and is suitable for public emergency communication and military communication guarantee and the like.
Description
technical field [0001] The invention relates to the field of antenna technology, in particular to a short-wave whip antenna, which can be used for public emergency communication and military communication guarantee. Background technique [0002] Short-wave communication has the characteristics of long communication distance, low operating cost, and convenient installation. It has important applications in public emergency communication and military communication support. Whip antenna is an important part of shortwave communication system. The shape of the whip antenna is a vertical slender rod, which has the advantages of small lateral size and simple structure. The performance of the whip antenna is closely related to the ratio between the length and the radio wavelength. In order to meet certain technical indicators, its length is generally larger. Existing whip antennas usually use a telescopic mechanism to realize folding and unfolding, or are artificially spliced by...
