Built-In Antenna

Built-in FPC antenna is manufactured with Flexible Printed Circuit (FPC) technology. Thanks to its ultra-thin profile, bendable texture and easy integration, it has been widely adopted in the wireless communication industry.

The built-in antenna is an antenna device integrated inside electronic equipment for receiving FM radio signals within the 76–108 MHz frequency band. It can replace traditional earphone wire antennas or external antennas, and is applied to electronic products such as mobile phones and portable radios.It captures radio waves via PCB traces, tiny metal sheets or special antenna structures. Restricted by electrical size effects, it suffers from drawbacks including low gain, narrow bandwidth and insufficient radiation efficiency. Besides, its signal reception is vulnerable to human body interference and signal shielding.

This utility model discloses a spring antenna, comprising a spring antenna body, a sleeving mechanism and a locking mechanism. A connecting wire core is fixedly mounted at the bottom end of the spring antenna body. The outer side of the joint between the spring antenna body and the connecting wire core is provided with the sleeving mechanism capable of adjusting the signal transmitting and receiving direction of the connecting wire core. The bottom of the inner cavity of the sleeving mechanism is equipped with the locking mechanism for fastening and fixing the connecting wire core, and the locking mechanism is arranged at the lower part outside the connecting wire core.Benefits of the utility model: The sleeving mechanism enables signal transmission and reception at any arbitrary angle and direction; the antenna can be bent freely and its orientation adjusted flexibly to improve signal transceiving performance and facilitate user operation. Relying on the threaded connection between the threaded pipe base and threaded adapter, a metal shaping hose can be sleeved outside the connecting wire core, so the hose can retain its bent shape at the required angle after bending.
