Patent ID: 7388543

Claim:
A multi-band radio antenna device for a radio communication terminal, comprising: an integral feed and ground structure electrically connected to a first radiating antenna element and a second radiating antenna element, said first radiating antenna element comprising a first continuous trace of conductive material, the first continuous trace having a first branch tuned to radiate at first frequencies in a first frequency band, and a second branch, which is tuned to radiate in a second frequency band at second frequencies approximately equal to or less than two times the first frequencies; and said second radiating antenna element comprising a second continuous trace of conductive material, the second continuous trace having a third branch, which is tuned to resonate in a third frequency band at third frequencies that are higher than the second frequencies, and is capacitively coupled to the feed and ground structure and arranged substantially adjacent to the second branch; wherein the first branch comprises a first section, composing approximately ⅓ to ⅔ of the total length of the first branch, wherein the first section is essentially straight and connected to said feed and ground structure at a first end thereof, and a second section in direct connection to a second end of said first section that is tightly meandered.
