Abstract
A parasitic dipole assisted WLAN antenna for creating a second resonance in the A band and providing greater bandwidth usage to a mobile computing or communication device. A secondary B/G band monopole antenna is connected to the A band antenna at the point of maximum impedance of the A band providing minimal interference between the two bands. The dipole structure antennas are connected at the A band loop antenna feed pin and ground pin.
