2. Description of the Prior Art
Communication technology utilizes mediums to transmit signals from a transmission end to a receiving end, wherein communication technology at least includes wire communication technology and wireless communication technology. Particularly, wireless communication technology generally provides convenience to people and is applied to network, telephone, laptop, tablet, or other mobile devices for fast information transmission.
In practical applications, wireless technology utilizes antenna modules to radiate electric signals for transmitting information, wherein the antenna module needs to connect a coaxial cable, and the coaxial cable is used for transmitting electric signals. In addition, RD firms try to research the connection method between the coaxial cable and the antenna module so as to simplify the assembling process. Most of the conventional connection methods utilize metal welding for connection, wherein metal welding can be manual metal welding or automatic metal welding. However, manual metal welding has faults of labor costs and low assembling efficiency; automatic metal welding is hard to be automatized.
some RD firms try to directly connect the coaxial cable and the antenna module bypassing the soldering process. However, a core wire and a ground weaving net of the coaxial cable easily fork or separate, so that the coaxial cable cannot easily connect the antenna module, reducing the assembling efficiency and radiation yield. For the above reasons, the conventional antenna module still has many defects.
