summary：
(1) Characteristics brought by environmental use: Considering the conditions of use of any mobile car, except for devices used in specific places such as ETC, the general vehicle antenna should be a non-directional antenna.
(1) Characteristics brought about by environmental use: consideringCarAny mobile usage conditions,ETCOther than the device used in a specific place, the general vehicle antenna should be a non-directional antenna. At present, the improvement of radio and TV receivers is being actively promoted, and some models use two antennas for radio reception and 3 to 4 antennas for TV reception. For the use environment, the antenna must have excellent water resistance, vibration resistance, corrosion resistance, etc., while also taking into account safety, wind noise and the impact on the vehicle shape.
(2) Features brought by the vehicle structure: The single-axis antenna that becomes the basis of the vehicle antenna should have a length of 1/4 of the wavelength of the received radio wave, but the length of the antenna that can be installed on the vehicle is only about 1m.
(3) Features brought by multimedia: multiple antennas should be installed in a limited position while considering ensuring the receiving performance of the antenna, preventing interference between the antennas, the feasibility of setting and the commercialization of the appearance.
Kind
(1) The column antenna is installed on the front column. It can be divided into the column embedded type and the column external type. Its structure is simple and the cost is low. Due to the inconvenience and unsightly appearance, the usage is gradually decreasing. It is mainly used for AM/FM radio.
(2) The roof antenna is installed on the roof. Because it is installed on the roof and relies on the rotating hinge, the inclination of the tie rod can be adjusted freely. It is used as a radio receiving antenna. Considering the three-dimensional parking lot and the shape of the hair surface, the total length is 200mm Antennas below are mostly used, mainly for AM/FM radios and telephones.
(3) The electric antenna is installed on the front fender and the rear fender. It is driven by a motor and the tie rod can be automatically expanded and contracted. It is divided into two types: radio-related operation and manual operation. It is mainly used for AM/FM radio.
(4) The windshield antenna is installed at the positions of the rear windshield, side windshield and front windshield, and metal wires are printed on the front windshield to become the antenna; when the area of the antenna type cannot be fully utilized and the sensitivity is insufficient, amplifiers or matching circuits are often used; in order to shorten the development cycle, the past test method is changed to modern development method, and the theoretical design method is introduced; mainly used for AM/FM radio, VICS, FM multiple, TV, telephone, remote control.
(5) The fender whip antenna is installed at the front fender and the rear fender, and an antenna is fixed on the front or rear fender. It is mostly installed on cars exported to North America and is mainly used for AM/FM radio.
(6) The plug-in antenna is installed on the instrument panel and the ceiling. The plug-in mode printed on the upper surface of the ceramic base plate and the antenna that supplies electricity between the ground planes on the back have certain directivity and are used at frequencies above GHz band. GPS, VICS radio beacon, ETC.
(7) The helical antenna is installed on the roof and is composed of a coil-shaped antenna. There are two ways to generate a linear partial wave in a plane perpendicular to the axis and a circular partial wave in the axial direction. It is mainly used for AM/FM radio, satellite radio.
(8) The horn antenna is installed in the front grille, and has a structural antenna with the front end of the waveguide tube gradually expanding outward. There are two kinds of antennas: circular and rectangular. It has a sharp directivity in the direction perpendicular to the opening. Frequency use in GHz band; Mainly used in microwave radar.
(9) The sheet antenna is installed at the front windshield, side windshield and rear windshield, and the metal conductor wire is printed on the transparent sheet and attached to the windshield glass; it is mainly used for microwave radar.
(10) The diversity antenna is installed at the pole glass and glass glass. When it is used for FM and TV, in order to prevent the problem of channeling, the multi-heel antenna works. Due to the installation of multiple antennas, the cost is relatively high. Mainly used for AM/FM radio and TV.
(11) The composite antenna is installed on the dashboard and the roof, and the antennas for various media are stored in one frame, thus realizing miniaturization and improving aesthetics. With Europe as the center, it is mostly used as a combination of telephone and GPS as a communication antenna. Due to the increase in the use of vehicle-mounted media, it is expected that the use will gradually increase in the future, mainly for AM/FM radio, GPS, telephone, satellite radio and ETC.
