Take you to understand the types of car antennas in one minute

What types of car antennas are there? Let's take a look at them together.

(1) The column antenna is installed on the front column, and can be installed in the column purchase type and outside the column. The structure is simple and the cost is low. Due to inconvenience and beautification, the usage is gradually reduced, and it is mainly used for AM/FM radio.

(2) The roof cover antenna is installed on the roof, and the inclination of the lever can be freely adjusted by rotating the hinge. As an antenna for radio pickup, considering the three-dimensional parking lot and the modeling head, the antenna with a total length of less than 200 mm is mainly used for AM /FM radio and telephone.

(3) The electric antenna is installed on the front and rear wings, driven by a motor, and the lever is automatically stretched. It is divided into two types: radio-related manual and manual. It is mainly used for AM/FM radio.

(4) The windshield antenna is installed on the rear windshield, side windshield and front windshield, and the metal wire is printed on the front windshield to become the antenna. The area of the antenna type is not fully utilized, and when the sensitivity is insufficient, amplifiers or matching circuits are often used. In order to shorten the development cycle, the past experimental method was changed to a modern development method, and a theoretical design method was introduced. Mainly used for AM/FM radio, VICS, FM multiple, TV, telephone, remote control.

(5) The fender whip antenna is installed on the front fender and rear fender, and an antenna is fixed on the front fender or rear fender, which is mostly installed on North American export vehicles, mainly used for AM/FM radio.

(6) The connecting antenna is installed inside the instrument panel and above the top cover. It is an antenna that supplies power between the plug pattern printed on the surface of the ceramic backplane and the ground on the back, and has a certain directivity at frequencies above the GHz band.

(7) The helical car antenna is installed above the top cover and consists of a coil-shaped antenna. There are two methods: a linear offset in the axial vertical plane, and a circular offset in the axial direction. Mainly used for AM/FM radio, satellite radio.

(8) The horn antenna is installed on the front grille, and the construction antenna with the front end of the duct gradually extending outwards has two types: circular and rectangular. It has a relatively sharp directivity in the direction perpendicular to the opening. The use of frequencies in the GHz band is mainly for microwave radar.

(9) The slicer antenna is installed on the front windshield, side windshield and rear windshield, and the wire of the metal conductor is printed on the transparent slicer and attached to the windshield. Mainly used for microwave radar.

(10) Diversity antennas are mounted on pioneer glass and glass glass, when used for FM and TV, multi-band antennas work to prevent channel problems. The cost is relatively high because multiple car antennas are installed. Mainly used for AM/FM broadcast TV.

(11) The composite car antenna is installed on the dashboard and the top cover, and various media antennas are gathered in the box to achieve miniaturization and improve aesthetics.
