Abstract
A multi-band antenna operates at a low frequency and a wider high frequency bands, which is formed as an elongated shape defining opposite ends. The multi-band antenna has a slot opened at a long edge and being extending to one end thereon. The wide range of the opening of the slot is larger than the extension length of the slot. A feeding conductor with a feeding point is arranged to adjoin the opening of the slot. The multi-band antenna resonates the low frequency band and a first high frequency. The slot obtains a second high frequency band higher than and partially overlapped the first high frequency. So the multi-band antenna has the low frequency bands and the better high frequency which includes several high frequency bands.
