Wireless electronic product with step-shaped wideband antenna

This invention is a wireless electronic product including a printed circuit board and a signal line installed at an end of the printed circuit board, wherein a wideband antenna is installed on the printed circuit board and has a shape extending from an another end of the printed circuit board towards the central position of the printed circuit board to form a symmetrical step-shaped antenna, and a microstrip feedline is extended from an end of the wideband antenna away from the another end of the printed circuit board and coupled with the signal line, such that the current produced by microstrip feedline due to an electro-inductive effect can flow along a step-shaped path on both sides of the wideband antenna, and the current can be distributed uniformly on the wideband antenna to effectively reduce the electro-inductive effect of the microstrip feedline.
