Abstract
The utility model belongs to the field of mobile communication, and particularly relates to a metal backing mirror used in the wave bands of HF, VHF, UHF and SHF for automobile mobile communication. The metal backing mirror (1) is inlaid in a plastic casing (6). The facade of the metal backing mirror is a metallic reflection mirror face, and the back side of the metal backing mirror is connected with an antenna radiating body composed of an antenna top load (3) and a built-in radiation fin (2). The radiation fin (2) is connected in series with a trimmer capacitor (4) and a loading coil (5) and is connected with an antenna feeder (9), and then is led in the automobile through a support frame (8) and a supporting seat (7) of the backing mirror. The utility model has the advantages of double purposes, scientific design, novel structure, convenience and practicability, and is suitable for the mobile communication of various automobiles.
Description
The utility model belongs to mobile communication, particularly a kind of automobile mobile communication metal side mirror antenna that is used for HF, VHF, UHF, the use of SHF wave band.
At present domestic and international automobile mobile communication antenna generally adopts to have the whip antenna of sucker or place roof as mobile communication antenna on extraordinary antenna.This antenna ubiquity and used trouble, and is disguised bad, subjects to damage the shortcomings such as overall appearance of overslaugh car body.
The purpose of this utility model is to overcome above technical deficiency, and the mobile communication metal side mirror antenna of a kind of height that gains, good concealment, a thing dual-purpose is provided.
For solving above-mentioned task, the utility model adds top load (3), built-in radiation fin (2) three parts formation antenna radiator by metal side mirror (1), antenna, and three parts are copper material, connect by brazing.Built-in radiation fin (2) other end and trimmer (4) and loading coil (5) are in series.The utility model major parameter performance realizes with metal side mirror (1) angle, physical dimension, geometry and trimmer by adjusting built-in radiation fin (2).Loading coil (5) other end connects feeder input (12), and feeder (9) is introduced in the car by side mirror bracing frame (8) and side mirror bearing (7).Built-in radiation fin (2), antenna add top load (3), trimmer (4), loading coil (5), all are built in the space that forms between metal side mirror (1) and the side mirror plastic casing (6).The automobile-used metal side mirror of mobile communication antenna, the front is a side mirror, is again the part of antenna radiator, and a thing dual-purpose has that gain height, isotropic directivity, volume are little, in light weight, a good concealment, characteristics such as not fragile.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Among the figure, 1-metal side mirror; The built-in radiation fin of 2-; The 3-antenna adds top load; The 4-trimmer; The 5-loading coil; 6-side mirror plastic casing; 7-side mirror bearing; The 8-bracing frame; The 9-feeder; 10-adjusts the hole; 11-adjusts the hole seal cover; 12-feeder input
Accompanying drawing 1, accompanying drawing 2 are the utility model structure charts, and accompanying drawing 3 is the utility model external form figure.
With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, mobile communication metal side mirror antenna is made up by the same side mirror of side mirror plastic casing (6) (1), side mirror (1) front of going up insert at plastic casing (6) is the metallic reflection minute surface, upper end, the speculum back side connects antenna and adds top load (3), and the lower end connects built-in radiation fin (2) and forms antenna radiator.Built-in radiation fin (2) other end is connected with trimmer (4), loading coil (5), and another termination feeder input (12) of loading coil (5), feeder (9) are through side mirror bracing frame (8), and bearing (7) is introduced in the car.Trimmer (4) is gone up by plastic casing (6) and is adjusted hole (10) adjustment antenna frequencies, improves the gain property, is seal cover (11) adjusting outer end, hole (10), waterproof sealing.
The key technical indexes:
Impedance 50 Ω
Gain 〉=4dB
Directivity omnidirectional
Standing-wave ratio≤1: 1.2
Mobile communication metal side mirror antenna, with the metal side mirror is antenna radiator, the front is a mirror surface, dual-use material, utilize the space of side mirror and housing, lay antenna radiator and loading, micromatic setting, design science, novel structure, practical and convenient are applicable to various, all kinds of automobile mobile communication at HF, VHF, UHF, SHF wave band.
Claims (2)
1. mobile communication that is used for HF, VHF, UHF, SHF wave band, make up by the same side mirror of side mirror plastic casing (6) (1), the metal side mirror antenna that bracing frame (8), bearing (7) are formed, it is characterized in that it is the metal eyeglass that side mirror plastic casing (6) is gone up side mirror (1) front of insert, upper end, the speculum back side connects antenna and adds top load (3), and the lower end connects built-in radiation fin (2) and forms antenna radiator.
2. mobile communication metal side mirror antenna according to claim 1, it is characterized in that built-in radiation fin (2) other end connects with trimmer (4), loading coil (5), another termination feeder input (12) of loading coil (5), feeder (9) is introduced in the car through side mirror bracing frame (8), bearing (7).
