Shark fin multifunction antenna for vehicles

Abstract

The invention discloses a shark fin multifunction antenna for vehicles and relates to the technical field of radio signal receiving antennae for the vehicles. The shark fin multifunction antenna for the vehicles is capable of enhancing electric signals and can be used for receiving cell phone signals, satellite navigation system signals and satellite digital signals. The shark fin multifunction antenna for the vehicles comprises a shark fin-shaped shell and a bottom plate, wherein the interior of the shell is of a groove structure; the bottom plate is arranged at the bottom part of the shell to seal a groove of the shell; a radio receiving antenna and an amplitude modulation frequency modulation circuit board are arranged in the groove of the shell; the radio receiving antenna and the amplitude modulation frequency modulation circuit board are connected together; a plate-like receiver, a satellite navigation system antenna, a satellite digital audio antenna, a cell phone signal antenna, a satellite navigation system circuit board, a satellite digital audio circuit board and a cell phone signal processing circuit board are also arranged in the groove of the shell; and the radio receiving antenna is a spiral coil or an inductive coil.

Description

technical field [0001] The invention relates to the technical field of antennas for radio signal reception for vehicles, in particular to a shark fin multifunctional antenna for vehicles. Background technique [0002] As we all know, the vehicle-mounted antenna is a device for receiving radio signals on the vehicle. It is widely used in vehicle technology. Long, the device on the vehicle not only affects the aesthetic effect of the vehicle, but also when entering various spaces, such as car washes and garages, due to its long length, it is often touched, which is inconvenient and damages the antenna itself. Shorter lifespan. [0003] Later, a shark-fin vehicle antenna appeared, including a shark-fin-shaped shell and a bottom plate. The inside of the shell is a groove structure, and the bottom plate is installed at the bottom of the shell to seal the groove of the shell. A fixing rod is installed on the bottom plate for fixing on On the vehicle, a radio receiving antenna an...

[0003] Later, a shark-fin vehicle antenna appeared, including a shark-fin-shaped shell and a bottom plate. The inside of the shell is a groove structure, and the bottom plate is installed at the bottom of the shell to seal the groove of the shell. A fixing rod is installed on the bottom plate for fixing on On the vehicle, a radio receiving antenna and an AM / FM circuit board are arranged in the groove of the shell, and the output end of the radio receiving antenna is connected with the input end of the AM / FM circuit board. This shark fin vehicle antenna is found in use, The radio receiving antenna is responsible for receiving and transmitting electrical signals and directly to the AM and FM circuit board. The signal effect is poor and the form is single, so it can only be used to receive broadcast signals
