ANTENNA FOR WIRELESS USB DONGLE DEVICE AND WIRELESS USB DONGLE DEVICE USING SAME

摘要

The present invention relates to an antenna for a wireless USB dongle device, and includes: a dielectric substrate; a first copy patch which is provided on one surface of the dielectric substrate and resonates in a first frequency band; a second copy patch which is near the first copy patch and resonates in a second frequency band, which is different from the first frequency band; a third copy patch which is connected to a middle portion of the first copy patch and resonates in a third frequency band, which is different from the second frequency band; and a ground plane to which the end terminal of the first copy patch is connected. Accordingly, the first to three copy patches allow resonance to occur in a triple frequency band, so that it is possible to be applied to a wireless USB dongle device which supports a service using a triple frequency band, i.e. using each of the 3.5GHzWiMAX (3.4-3.6 GHz), WiBro (2.3-2.39 GHz), WLAN (2.4-2.483 GHz, 5.15-5.825 GHz), 2.6GHzWiMAX (2.5-2.7 GHz), S-DMB (2.605-2.655 GHz), and ISM/Bluetooth (2.4-2.480 GHz).
