Patent ID: 7782258

Claim:
An integrated antenna for worldwide interoperability for microwave access (WiMax) and wireless local area network (WLAN), comprising: a substrate, having a first surface; a grounding metal strip; a first radiating metal strip, disposed on the first surface of the substrate and not connected to the grounding metal strip, wherein the first radiating metal strip has a first portion for inducing a first resonance mode and a second portion for inducing a second resonance mode on two ends thereof, the second portion has a first end and a second end, the first end is connected to the first portion, the second end has a second end face and a second extension portion extending in a first direction, the width of the second end is greater than that of the second extension portion; and a second radiating metal strip, disposed on the first surface of the substrate and connected to the grounding metal strip, wherein the second radiating metal strip is not connected to the first radiating metal strip, the energy is coupled from the second radiating metal strip to the first radiating metal strip to induce a third resonance mode, the second radiating metal strip has a third end and a fourth end, the third end is connected to the grounding metal strip, the fourth end is perpendicular to the third end, the fourth end has a fourth end face and a third extension portion extending in a second direction opposite the first direction, the third extension portion is perpendicular to the fourth end face, the width of the fourth end is greater than that of the third extension portion, the third extension portion faces the second end face, the second extension portion faces the fourth end face, and the second extension portion is parallel to the third extension portion and is spaced from the third extension portion by a pitch.
