Abstract
The present invention discloses a pendulum-shaped microstrip antenna structure which is manufactured in form of a metal microstrip on a side of the printed circuit board and installed at a distal end of the printed circuit board, when the pendulum-shaped antenna is installed onto a printed circuit board of a wireless electronic product. The pendulum-shaped microstrip antenna structure includes a signal feeding portion and an antenna portion sequentially installed in the direction from the printed circuit board to its distal end, and the pendulum-shaped antenna is extended outward, so that a current transmitted from the pendulum-shaped antenna can be distributed uniformly onto the signal feeding portion and the antenna portion to achieve the effects of improving the bandwidth of the pendulum-shaped antenna, reducing the feeding inductance, and providing sufficient bandwidth for the antenna.
