Abstract

An integrated multi-band antenna has a first radiating element and a second radiating element. The first radiating element has a first radiating conductor defining opposite sides connected to a second radiating conductor and a third radiating conductor respectively. A fourth radiating conductor defines a first end facing the free end of the third radiating conductor. A fifth radiating conductor connects the third radiating conductor and vicinity of the first end of the fourth radiating conductor. A sixth radiating conductor connects the first radiating conductor and close to a ground portion. The second radiating element has a seventh radiating conductor staggered opened plurality of slots at opposite sides thereon. An eighth radiating conductor connects the seventh radiating conductor and the ground portion. The integrated multi-band antenna operates at wireless telecommunication frequency through the first radiating element and operates at wireless local area network frequency through the second radiating element.
