Description
Technical field
It the utility model is related to antenna technical field, more particularly to a kind of Big Dipper location navigation antenna.
Background technology
With the development in pluralism of automobile industry, car antenna is also constantly updating, and weeds out the old and bring forth the new.Previous car
The performance of single gps antenna can only be realized by carrying antenna, and the appearance of Beidou navigation, drive the development of Beidou antenna.Gradually
The research and development of double frequency, multifrequency antenna is gradually permeated so that the Big Dipper/GPS (Global Positioning System, the whole world
Alignment system) research and development with application turn into development trend.
The assembling of traditional Big Dipper location navigation antenna upper and lower covers is using the mode of the turn of the screw, this assembling mode behaviour
Make comparisons cumbersome, spend time length, manufacturing schedule cannot be lifted, and also add artificial Material Cost.In process of production, such as
Fruit misoperation, product can be made to sustain damage.Moreover, the air-tightness of product, the uniformity of waterproof effect can not ensure.These are asked
Topic has a very big impact to production efficiency.And the installation of vehicle-mounted reception antenna employs magnet, and because the magnet of routine divides S
Pole and N poles, this two-stage are mutually exclusive.So that after magnet uses long-time, magnetic can weaken, or even meeting demagnetization, so as to cause
Antenna is shifted or come off, and this can influence the performance of antenna.Simultaneously as the inner space of the shell of vehicle-mounted reception antenna is basis
The size of pcb board and the size of potsherd/highly are designed, it may be said that are to have shaped, it is difficult to change other chis
Very little pcb board.If change other sizes pcb board, it is necessary to re-start shell die sinking.These are all people in the art
Member does not expect what is seen.
