In order for wireless communication devices to be compatible with Bluetooth and 802.11a/b/g protocol standards, antennas that cover their respective frequency bands need to be designed. [0003] Since the electrical volume of the antenna / (band X gain X efficiency) = constant, the planarization of the antenna 'after miniaturization, the frequency band covered by it must be reduced. How to design a planar antenna that is small in size and can meet the above-mentioned agreement standards has become a major topic in antenna design. • r [0004] / ' : [New content] In view of this, it is necessary to provide a dual-band antenna with a small volume and a working frequency band that can comply with the protocol standard of Bluetooth and 802.11a/b/g.
