A novel dual resonant antenna configuration for mobile laptop, notebook and palmtop computers

A novel dual resonant internal antenna configuration was developed to cover all the important applications in multi-standard multifunction mobile laptop, notebook and palmtop computers. Only two wideband antennas covered the whole band from 470 MHz to 2.7 GHz, which was divided into two sub-bands. The low sub-band was from 470 to 960 MHz and the high subband was from 1.2 to 2.7 GHz. These frequency sub-bands could be adjusted according to the wireless applications that were needed to be covered. The two antennas might be utilized together or only one of them might be required depending on the number of wireless applications in the portable computer. Also, a triple antenna configuration might be used in order to add more applications.
