Automotive Combined Antenna

Abstract

The invention discloses an automotive combined antenna. The atuomotive combined antenna is a fin-shaped combined antenna for receiving a frequency modulating signal, a China mobile multimedia broadcasting signal, a global positioning system signal and a global mobile communication system signal. The automotive combined antenna comprises the components of: an amplitude / frequency modulation receiving part which is used for receiving amplitude / frequency modulation signal; a China mobile multimedia broadcast receiving part which is used for receiving a China Mobile multimedia broadcasting signal; a global positioning system receiving part which is used for receiving a global positioning system signal; a global mobile communication system / universal mobile communication system which is used for receiving the global mobile communication system / universal mobile communication system signal; and a power supply part which is used for supplying power to the amplitude / frequency receiving part. Therefore, the automotive combined antenna has an advantage of no requirement for forming a single antenna according to each wireless service.

Description

technical field [0001] The present invention relates to a vehicle antenna, and more specifically, to a vehicle combined antenna capable of receiving signals in multiple frequency bands. Background technique [0002] China Mobile Multimedia Broadcasting (CMMB, China Mobile Multimedia Broadcasting) is designed to provide audio, video and With the advent of the multimedia era and the commercialization of various services such as mobile communications, the satellite and terrestrial wireless mobile broadcasting system for data services is also equipped with the development of new electronic products suitable for such vehicles and mobile broadcasting systems based on them. Equipment for communication technology. [0003] In addition, in order to meet the various needs of consumers, electronic products for new applications such as vehicle network, TV reception, navigation system, and digital multimedia broadcasting (DMB, Digital Multimedia Broadcasting) are being developed. There...

Problems solved by technology

However, the method of installing separate antennas capable of receiving each signal in the vehicle is not preferable in terms of vehicle design or space application.

[0004] Therefore, there is a need for a vehicle antenna system for new applications such as a vehicle network, TV reception, navigation system, and digital multimedia broadcasting for various wireless services provided in a vehicle. complex and diverse

[0005] However, in conventional antenna systems for vehicles, such receiving antennas for various wireless services are individually formed for each wireless service.

[0006] However, in the conventional antenna system for vehicles as described above, there are structural problems related to the installation in the limited space of the vehicle, such as the method of embodying individual antennas for each wireless service.
