Description
Technical field
The utility model relates to signal receiving device, especially relates to a kind of shark fin type car antenna that is used to receive the AM/FM signal.
Background technology
At present, the car antenna of shark fin type mostly is the antenna of GPS and GSM type, and the antenna of a spot of AM/FM of being and AM/FM/GPS type is also arranged.Because the cause that the AM/FM antenna wavelength is long requires antenna length longer usually, overall dimension is bigger.And the car antenna of shark fin type has limited size because of appearance requirement, so the reception of the AM/FM antenna of a lot of shark fin types is undesirable.
The common AM/FM car antenna in market has type of antenna such as coiling on the minor diameter of employing helical spring, the bar magnet, full wafer rain cone dress iron plate, the little band of PCB; All can not the not enough problem of fine solution antenna resonance length; Cause reflection excessive; Receptivity is poor, simultaneously the more high inherent shortcoming of antenna difficult installation cost.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of shark fin type car antenna that is used to receive the AM/FM signal to be provided.
The purpose of the utility model can realize through following technical scheme:
A kind of shark fin type car antenna that is used to receive the AM/FM signal; Comprise construction package and electric component; Described construction package comprises case and base, and described case and base are connected to form a closed cavity, and described electric component is located in the closed cavity; This electric component comprises reception antenna and signal amplifier module; Described reception antenna comprises metal radiant body, metal coiling and PCB track, and described signal amplifier module comprises interconnective syntonizing coil and signal amplifier, and described metal radiant body, metal coiling all are connected with syntonizing coil with the PCB track.
Described metal coiling is located at the inwall of case.
Described case is provided with the keeper that is used for fixing metal coiling, PCB track and metal radiant body, and described base is provided with the draw-in groove that is used for fixing signal amplifier, and described PCB is provided with and is used for the through hole that the metal coiling is passed.
This car antenna also comprises the sealing ring that is used for waterproof, and the sealing circle is located at the junction of case and base.
This car antenna also comprises the extended antenna module, and described extended antenna module is located in the seal chamber, and is fixed on the base.
