    • A dual-band antenna (1) for communication device includes a first radiating element portion (10) operating at a first frequency band, a second radiating element portion (20) operating at a second frequency band, an L-shaped ground portion (40), a conductive connection (50) interconnecting the first and second radiating element portions (10, 20) with the ground portion (40) and a slot (101) served as an impedance transformer and positioned on the ground portion (40). The slot (101) is implemented as a capacitive load that eliminates the inductive part of the input impedance of the antenna, thereby the slot (101) can match the input impedance of the antenna with a feed line.
    • 一种用于通信设备的双频带天线(1)包括在第一频带上操作的第一辐射元件部分(10),在第二频带操作的第二辐射元件部分(20),L形接地部分 ),将第一和第二辐射元件部分(10,20)与接地部分(40)互连的导电连接(50)和用作阻抗变压器并位于接地部分(40)上的槽(101)。 槽(101)被实现为消除天线的输入阻抗的感应部分的电容性负载,从而槽(101)可以将天线的输入阻抗与馈线相匹配。

    • A dual-band antenna can be used in wireless communications under Bluetooth and IEEE 802.11a/b/g standards includes a rectangular base (1) forming a transverse bar (5) and a grounding bar (41) extending therefrom in a same direction, a radiating portion (2) arranged distantly above the base, an interconnection bar (3) connecting the base and the radiating portion and a feeder cable (6). The radiating portion includes a first and a second radiating arms extending from the interconnection bar in opposite directions. The first and the second radiating arms, the interconnection bar, the transverse bar, the grounding portion and the feeder cable corporately form a first and a second inverted-F antennas respectively operating at a lower frequency band and a higher frequency band.

    • An external antenna (100) for a wireless communication device includes a dielectric base (1), a rotatable portion (2) received in the base, a connecting portion (3) connected with the rotatable portion and an antenna element (4) connected with the connecting portion. The dielectric base defines a bore (10) and a groove (12) therein. The rotatable portion includes an upper portion (21) and a block (23) extending from the rotatable portion and slidably engaging in the groove for limiting a rotational movement of the rotatable portion relative to the dielectric base. The connecting portion has an engaging portion (30) connected with the upper portion of the rotatable portion.
