Abstract

The invention provides a transmission line capable of lowering loss. The transmission line capable of lowering loss comprises a transmission part and connector parts, wherein the connector parts are arranged at two ends of the transmission part and are connected with a mobile terminal, the transmission part comprises a signal core used for transmitting signals, signal earth layers arranged at one side or two sides of the signal core, medium layers arranged at one side or two sides of the signal core and located between the signal earth layers and the signal core, protective layers arranged on the outer surface of the transmission part, and a bonding structure used for bonding the two medium layers at the upper side and the lower side of the signal core, the bonding structure comprises two mutually independent parts and is located at two sides of the signal core in the horizontal direction. The transmission line capable of lowering loss adopts the bonding structure comprising the two mutually independent parts and located at two sides of the signal core in the horizontal direction, the signal core is guaranteed to be separated from the bonding structure, the influences of bonding materials on the signal core are reduced, and therefore inserting loss of the transmission line is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of mobile phone antenna design, in particular to a transmission line with reduced loss. Background technique [0002] An antenna is a device that uses frequency characteristics to receive and transmit signals. In recent years, the design and performance of mobile terminal antennas for wireless communication have more and more influence on the development direction of mobile communication. Especially portable mobile terminals such as mobile phones, PDA (Personal Digital Assistance), MP3 / MP4. The main indicators of the antenna design are: there is a suitable multi-frequency resonance, and the antenna realizes signal propagation and energy radiation based on the resonance of a certain frequency. If an antenna can resonate at multiple frequencies, then the antenna will work at multiple frequencies. [0003] In recent years, more and more wireless terminals adopt a low-profile structural design. That is, the ...
