Problems solved by technology

The existing shark fin antenna is limited by its own volume, and it is impossible to set up a vibrator to receive a variety of different signals (such as GPS signals, 3G signals, etc.) in its limited internal space
Even setting it reluctantly for reception will result in extremely poor reception and extremely poor user experience
[0005] For the above problems, there is no good solution in the prior art

Abstract

The invention discloses a radio communication oscillator and a short vehicle-mounted antenna. The radio communication oscillator comprises a sleeve loading structure and a helical structure which are connected to each other. The sleeve loading structure comprises an inner sleeve, an outer sleeve, and a loading sheet, wherein one end of the inner sleeve is connected with the surface of the loading sheet, and the other end of the inner sleeve is fixed on a mounting plate; and the outer sleeve is fixed on the mounting plate and is in a common-ground state with the mounting plate; and the outer sleeve sleeves one end, far from the loading sheet, of the inner sleeve, and is not contacted with the inner sleeve. Through the above technical scheme, the radio communication oscillator is wideband due to the sleeve loading structure and the helical structure, and the broadband can cover all frequency bands needed by 4G, 3G and 2G communication. As a result, the radio communication oscillator is suitable for achieving 4G communication and is downwardly compatible with the 3G and 2G communication simultaneously.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a wireless communication vibrator and a low-profile vehicle antenna. Background technique [0002] With the development of the automobile industry and the popularization of automobiles, people's requirements for automobile comfort, safety, convenience and intelligence are increasing. In order to meet people's requirements for the use of vehicles, manufacturers have installed various vehicle-mounted devices (such as AM / FM radios, GPS navigation equipment, vehicle-mounted TVs, etc.) inside the vehicle, and installed receiving antennas outside the vehicle. [0003] Early external receiving antennas for vehicles include rod-type, telescopic rod-type, etc. These antennas are easily deformed or even damaged by external forces, and affect the appearance of the vehicle. For this reason, a shark-fin antenna is provided in the prior art to take into account both the function of the a...
