A multi-band radio antenna device for a radio communication terminal is
disclosed. The antenna has an integral feed and ground structure
electrically connected to a first radiating antenna element and a second
radiating element. The first radiating element comprises a first
continuous trace of conductive material and has a continuous trace has 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. The second radiating antenna element
comprises a second continuous trace of conductive material, wherein the
second continuous trace has a third branch, which is tuned to resonate in
a third frequency band at third frequencies that are higher than the
second frequencies, and which is capacitively coupled to the feed and
ground structure and arranged substantially adjacent to the second
branch. The first branch comprises a first section, composing
approximately 1/3 to 2/3 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.
