ABSTRACT:
Mobile terminals having a plurality of planar inverted-F antennas placed in close proximity of each other and methods of fabricating and using such mobile terminals are provided. Generally, planar inverted-F antennas, such as dual band CDMA, GPS, and Bluetooth antennas, cannot be placed in close proximity of each other without having interference. Accordingly, notch filters are provided in a dual band CDMA antenna to mitigate the interference and to facilitate isolation between the antennas.
