Abstract: A multiple frequency band planar antenna formed on one-side surface of a circuit board comprises: a first antenna pattern, a second antenna pattern, a third antenna pattern and a fourth antenna pattern, each antenna pattern further comprising an elongated portion and a conductor portion; wherein the second elongated portion at a point between its two ends is short-circuited to a feeding transmission line formed on another-side surface of the circuit board through a via. Thus, the multiple frequency band planar antenna can operate at three frequency bands with their central frequencies at 2.4 GHz, 3.5 GHz and 5.8 GHz, respectively, suitable for both WIFi LAN and WiMAX MAN applications.

Abstract: The present invention provides a wireless transmit/receive unit, comprising a feeding connecting line, a first radiating line, a second radiating line, a third radiating line and a fourth radiating line, wherein the third radiating line is longer than the first radiating line and the first radiating line is longer than the second radiating line that provides different current paths for getting a broader bandwidth. The first, second and third radiating lines are connected parallel for enhancing an antenna pattern being perpendicular thereto, and form a series capacity between the first and the third radiating lines. The fourth radiating line vertically connects between the third radiating line and a grounding line for forming a grounding capacity. The printed antenna can be reduced in size by the effect of the two capacities. The wireless transmit/receive unit can provide a better isolation with others by the direction enforced pattern and the reduced size.
