ABSTRACT:
An integrated antenna for worldwide interoperability for microwave access (WiMax) and wireless local area network (WLAN), includes a substrate, a grounding metal strip, and first and second radiating metal strips. The first radiating metal strip is disposed on the substrate and is not connected to the grounding metal strip. The first radiating metal strip has a first portion and a second portion on two ends thereof. The first and second portions are used to induce first and second resonance modes, respectively. The second radiating metal strip is disposed on the substrate and is connected to the grounding metal strip. 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 antenna is adapted to the frequencies of WiMax and WLAN.
