Re-configurable array from distributed apertures on portable devices
View Patent ↗The present invention features novel methods of implementing configurable arrays for personal portable devices including hand-held mobile devices and re-locatable wireless devices, utilizing a wireless communications system that employs multiple individual hubs and/or base-stations. The digital beam forming (DBF) methodology utilizes multiple low gain elements conformal to the mechanical contours of handheld devices to function as arrays. The distributed N element arrays dynamically provide the options of reconfigurable shaped beams with near hemispheric radiation patterns for various handheld orientations and conditions by various users, while also supporting operations of multiple orthogonal beams concurrently connecting to multiple hubs. The larger the N becomes, the more flexibility the residing devices can provide.
