Description

  The present invention relates to a structure of a flexible antenna, and in particular, a flexible structure that is simple in structure and can be curved as necessary to meet the needs of radio wave transmission in different environments. Related to sex antennas.

  The structure of the antenna applied to conventional radio wave transmission is relatively simple, and a thin multi-core metal conductor with insulation on the outer surface is connected to the input end of the radio wave receiver or the output end of the radio wave transmitter, Some metal conductors having this electromagnetic wave sensitivity characteristic replace antennas. However, such multi-core metal conductors themselves do not have adequate support strength, and unless they are supported by an external structure, they can only be coupled to a radio wave transmission device in a drooping manner. It is difficult to adjust the direction of transmission, which greatly affects the overall radio wave transmission effect.

  In addition, a relatively common length of an antenna or a telescopic antenna that can change the length, the length of the antenna is a metal or carbon fiber with direct elasticity in an elongated shape with a constant length. It can be made to have electromagnetic wave sensitive characteristics and get the function of radio wave transmission, but the metal or carbon fiber antenna with such elasticity is difficult to bend and keep its shape, and the radio wave transmission direction can also be adjusted Since it is difficult, many antennas having a constant length are used in a wide space environment, and the radio wave transmission effect is limited. In addition, the telescopic antenna overlaps a plurality of metal tubes and provides a stopper inside each metal tube to change the length of the metal tube while taking care not to separate the metal tube from the metal tube combined outside. The structure that can be formed. At the same time, most of these telescopic antennas are generally provided with a rotation mechanism at the base, which allows the telescopic antenna to be rotated and rotated 360 degrees to improve convenience in adjusting the radio wave transmission direction. ing. However, such an extendable antenna has a constant linear extension length when stretched or contracted, and is stretched in an environment where the surrounding space is insufficient. There is also a restriction on the length, which has a bad influence on the radio wave transmission effect and quality.

  In view of the above-mentioned drawbacks of the conventional antenna structure, the present invention has been born through research and improvement on these drawbacks.

  The main object of the present invention is to provide a flexible antenna that can be bent by the action of an external force and retain its shape, and that can be changed in accordance with the size of different environmental spaces. .
