Abstract
A multi-band antenna structure includes a substrate having a first wiring area located on one side surface thereof. The first wiring area has a first metal trace, a second metal trace and a connecting portion formed therein. The first and the second metal trace are respectively in an elongated spiral pattern; and the connecting portion is electrically connected at two opposite ends to the first and the second metal trace. The multi-band antenna structure can be directly integrated into electrical circuits on a circuit board to provide the advantages of reduced manufacturing cost and capable of transmitting or receiving multiple bands of signals.
