Problems solved by technology

Since the antenna protrudes from the surface of the car shell, it may affect the aerodynamics of the car
Moreover, there are strict requirements on antenna size, strength and environmental adaptability, which greatly limit the application of antennas in high-speed vehicles

Embodiment 1

[0018] Embodiment A kind of antenna for automobile

[0019] Such as figure 1 Shown: an antenna for a car, the antenna includes a radio frequency cavity 1 , a radome 2 , a radiator 3 and a radio frequency socket 4 . The radio frequency cavity 1 is made of anti-rust aluminum, and the sunken part at the top is used to connect with the radome 2, and a mounting hole for connecting with the carrier is reserved on the upper edge. The edge portion of the radome 2 is connected with the upper edge of the radio frequency cavity 1 by rivets to protect the internal radiator 3 and the radio frequency socket 4. As a preference, the radome 2 is composed of a hollow shell and a foaming material, and the foaming material is filled Sealed inside the radome 2 to increase the intensity of the radiator. The radiator 3 is an all-metal structure similar to an inverted F shape, which is arranged inside the radio frequency cavity 1. The radiator 3 includes an inverted cone 31, a top disc 32, a ground...

Abstract

The present invention provides an antenna for automobiles, which includes a radio frequency cavity, a radome, a radiator and a radio frequency socket, the radome is covered above the radio frequency cavity, and the radiator is arranged on the radio frequency cavity Inside, the radiator includes an inverted cone, a top disc, a grounding post and a metal plate. The upper end of the inverted cone is a large-diameter end, and the lower end is a small-diameter end. connection, the disc center part of the lower disc surface of the top disc is connected with the upper cylindrical surface of the grounding column, and the lower cylindrical surface of the grounding column is fixed on the inner bottom surface of the radio frequency cavity, the metal plate is parallel to the top disc, and the metal plate One end is welded on the side of the inverted cone, and the other end of the metal plate is welded on the side surface of the grounding post. The invention has the outstanding advantages of being conformal to the surface of the automobile body, compact in structure and small in size.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna for automobiles. Background technique [0002] With the continuous improvement of the top speed of cars, especially super sports cars, some top speeds have exceeded 400km / h. At such a high speed, the air resistance can no longer be ignored. Therefore, the requirements for the shape of the car are increasing, and the requirements for the functional performance, weight, and installation size of the antenna on the car are also getting higher and higher. As an important part of the radio transceiver system, its antenna is developing in the direction of aperture integration, compact structure, and minimization of vehicle aerodynamic disturbance. [0003] Automotive antennas are usually vertically polarized omnidirectional antennas, which use monopole antennas that resonate in the working frequency band to receive and transmit radio frequency signals. The antenna is compo...
