AFB-021A is a small terminal antenna with high anti-interference adopts coupling feed to improve the performance of the antenna.
The high radiation efficiency of the antenna solves the problem that the performance of the POS machine’s antenna is seriously deteriorated due to the long coaxial line.
In the small POS machine, the products are mainly in the form of bracket +FPC, and a miniature dipole antenna is developed to make its parameters must be good to ensure the stability of communication.
