Abstract
The utility model relates to a spiral telescopic antenna for a hand transceiver, comprising a telescopic antenna, a spiral coil and a loading coil. The telescopic antenna is embedded in the spiral coil and is connected with the spiral coil, and the spiral coil is connected with the loading coil. Therefore, the utility model can be retractably used, and meanwhile, the utility model has the advantages of high gain of the telescopic antenna, short selfresonance of the configuration of the spiral antenna, convenient use, etc.
Description
The utility model is a kind of hand-held intercom spiral telescopic antenna.
At present, the antenna of hand-held intercom is to adopt helical antenna or telescopic antenna.The shortcoming of helical antenna is: the horizontal direction gain is low.The shortcoming of telescopic antenna is: only pull out Shi Caineng and be transferred to resonance frequency, it is very low to gain after shrinking, and uses inconvenience etc.
The purpose of this utility model is exactly to provide a kind of hand-held intercom spiral telescopic antenna in order to overcome above-mentioned weak point.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model profile schematic diagram when pulling out.
Fig. 2 is that the utility model shrinks back profile schematic diagram.
Fig. 3 is a structural representation of the present utility model.
Referring to Fig. 3, the utility model is made up of telescopic antenna (1), spiral winding (2) and loading coil (3), telescopic antenna (1) is assembled in the spiral winding (2), telescopic antenna (1) interconnects respectively with loading coil (3) with spiral winding (2) and spiral winding (2), and the other end of loading coil (3) is connected with socket (4).
Referring to Fig. 1, Fig. 2, when using the utility model, be connected with hand transceiver by socket (4), just can be transferred to resonant frequency during pull-up telescopic antenna (1), thereby improve the horizontal direction gain of antenna and the gain of antenna, gain can reach about 3 decibels, is the little self-resonance helical antenna of a kind of electricity when shrinking telescopic antenna (1), and the effect of loading coil (3) is the gain that makes antenna and hand transceiver input and output impedance phase coupling and raising antenna.
Great advantage of the present utility model is: scalable use, have the characteristics of the short self-resonance of telescopic antenna high-gain and helical antenna profile simultaneously, and easy to use etc.
Claims (1)
1, a kind of hand-held intercom spiral telescopic antenna, it is characterized in that forming by telescopic antenna (1), helical coil (2) and loading coil (3), telescopic antenna (1) assembly is in helical coil (2), and telescopic antenna (1) interconnects respectively with loading coil (3) with helical coil (2) and helical coil (2).
