A dual antenna configuration for multi-standard multifunction handsets and portable computers

A novel dual antenna configuration has been developed for multi-standard multifunction mobile handsets and portable computers. Only two wideband antennas cover a frequency band from 470 MHz to 3.6 GHz, which is divided into two sub-bands; 470 - 960 MHz and 1.57 - 3.6 GHz. The new antennas are low-cost multi-polarized unbalanced resonant antennas that do not need matching circuits or any other components. Their overall sizes are very small and they do not require additional extended ground planes. They are made of a flexible material and hence they can be easily bent and/or folded in different forms in order to fit inside any mobile handset, laptop, notebook or palmtop computer.
