Connector and electronic system using the same

This invention relates to a connector and its electronic system, and more particularly to a high frequency connector and its electronic system.

Conventionally, when high-frequency signal transmission or connection of several different electronic communication products is made, a coaxial cable is usually used as a connector. However, the coaxial cable connector is bulky and takes up space, and is difficult to apply to portable electronic devices such as mobile phones. On the other hand, because the structure of the coaxial cable connector is fixed and lacks variability, it is difficult to meet the customization requirements of various customers for various products, and the manufacturing cost is also high.

In addition, the coplanar waveguide technology is another commonly used high-frequency signal transmission technology, which is characterized in that it is a single-plane transmission line, that is, the signal line and the ground line are all in the same plane, so that the series and parallel connection between the electronic components are very easily. Moreover, the electrical characteristics of the electronic components using the coplanar waveguide technology are not affected by the thickness of the dielectric plate, and the cost of fabricating the circuit can be greatly reduced, and the selectivity of the circuit layout can be greatly increased.
