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 0.6mm.
[0020] The principle of the inner bistable composite tube 2 and the outer bistable composite tube 3 is as follows: the composite open...

Abstract
A portable composite material short wave whip antenna device is composed of a bistable composite material pipe, a copper wire, a root end cover, a top end cover, a fixing rope and fixing nails. According to the invention, the bistable composite material pipe is introduced as a support structure of the whip antenna. The copper wire is embedded into the composite material pipe. During transportation, the copper wire and the bistable composite material pipe are curled together to be stably stored without additional structural constraints. The weight of the whip antenna device is reduced. The sizeof the whip antenna device during transportation is reduced. During usage, the bistable composite pipe in a curled state is unfolded and the openings of two bistable composite material pipes are oppositely inserted. A root end cover and a top end cover are installed. One end of the copper wire makes contact with a prefabricated feed interface in the root end cover. The end cover and the bistablecomposite pipes are locked through a locking hoop. The fixing rope is tied to the top end cover and the bistable composite pipes are erected. The root end cover and the fixing rope are fixed through fixing nails respectively. The portable composite material short wave whip antenna device has the advantages of being light in weight, small in transportation size, convenient to carry, easy to erect and the like, and is suitable for public emergency communication, 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...
