Introduction to Types of Auto Antenna

For cars, we all know more or less. After all, cars are the most common means of transportation, but have you ever observed that all cars have antennas? What are the types of car antennas? As a leading Auto Antenna Mast supplier, let's introduce it to you today.

Different types of Auto Antenna

• The column antenna is installed on the front column, which can be divided into column embedded type and column external type. It has a simple structure and low cost. Due to inconvenient and unsightly use, the usage is gradually decreasing. It is mainly used for AM / FM radio.

• The roof antenna is installed on the roof. Because it is installed on the roof, the inclination of the pull rod can be adjusted freely by rotating the hinge. As an antenna for radio reception, considering the three-dimensional parking lot and modeling surface, the antenna with a total length of less than 200mm is widely used, which is mainly used for AM / FM radio and telephone.

• The electric antenna is installed on the front fender and rear fender, driven by the motor, and the pull rod can expand and retract automatically. It is divided into radio linkage and manual. It is mainly used for AM / FM radio.

• The windshield glass antenna is installed at the rear windshield, side windshield, and front windshield, and the metal wire is printed on the front windshield glass to become the antenna; When the area of antenna type can not be fully utilized, resulting in insufficient sensitivity, amplifiers or matching circuits are often used; To shorten the development cycle, the past test method is changed to modern development method, and the theoretical design method is introduced; It is mainly used for AM / FM radio, VICS, FM multiple, TV, telephone and remote control.

• The fender whip antenna is installed at the front fender and rear fender. One antenna is fixed at the front or rear fender. It is mostly installed on vehicles exported to North America and is mainly used for AM / FM radio.

• The plug-in antenna is installed in the instrument panel and on the roof. The plug-in model printed on the upper surface of the ceramic base plate and the antenna that supplies power between the background have certain directivity and can be used at frequencies above GHz band; GPS, VICS radio beacon, etc.

• The spiral antenna is installed on the roof and is composed of a coil antenna. There are two ways to generate a linear bias wave in the vertical plane with the axis and a circular bias wave in the axial direction. It is mainly used for AM / FM radio and satellite radio.

• The horn antenna is installed on the front grid and has a structure antenna with the front end of the waveguide gradually expanding outward, including circular and rectangular antennas; It has sharp directivity in the direction perpendicular to the opening; Frequency use in GHz band; It is mainly used for microwave radar.

• The sheet antenna is installed at the front windshield, side windshield, and rear windshield, and the conductor of the metal conductor is printed on the transparent sheet and pasted on the windshield glass; It is mainly used for microwave radar.

• The diversity antenna is installed at the pole + glass and glass + glass. When used for FM and TV, to prevent the problem of channel shifting, make the multi-channel antenna work; Due to multiple antennas, the cost is relatively high; Mainly used for AM / FM radio and TV.

• The composite antenna is installed in the instrument panel and on the roof, and the antenna for various media is stored in a frame, which realizes miniaturization and improves the degree of beauty; Centered in Europe, as a communication antenna, it is mostly used in the combination of telephone and GPS; Due to the increase in the use of vehicle media, it is expected that the user will gradually increase in the future, mainly for AM / FM radio, GPS, telephone, satellite radio, etc.
