Patent abstract
A wide frequency band planar antenna comprises an elongated portion, substantially parallel to a circumferential edge of a ground pattern and comprising one end connected to a feeding transmission line, wherein there is a gap between the elongated portion and the circumferential edge of the ground pattern; a body stub and an impedance-matching-adjusting pattern for adjusting an impedance matching between the wide frequency band planar antenna and the feeding transmission line; wherein the gap value is less than 2 mm so as to enable the wide frequency band antenna to operate at a wide range of frequencies ranging from 2.3 GHz to near 6 GHz, thereby allowing the wide frequency band antenna to be applied in both WiFi LAN and WiMAX MAN.
