Abstract

An integrated diversity antenna solution is presented that positions multiple antennas within the digital device case. The integrated diversity antenna solution works equally well with diversity radios, such as 802.11, and non-diversity radios, such as Bluetooth. The non-diversity radios are supported via a power splitter attached to the antennas that give the necessary directional coverage. The integrated antenna array solves the main problem associated with wireless communication on laptop computers, specifically, that laptops perturb the radiation pattern because of the influence that laptop components have on standard antennas and the presence of interfering objects, most notably the laptop user, in the surrounding environment.
