20120071214 | Inductively Coupled Signal Booster For A Wireless Communication Device And In Combination Therwith - A passively re-radiating cell phone sleeve assembly capable of conforming to and nesting with a cell phone provides a partial enclosure capable of fitting over at least a portion of the cell phone. A multi-layer radio frequency (RF) coupling probe is fully embedded within the enclosure in a position that is in close proximity to an internal antenna of the cell phone when the enclosure is nested with the cell phone. A coupling probe is inductively coupled to the internal antenna for sharing RF signals and is desensitized from de-tuning the internal antenna of the cell phone. An external antenna is mounted on the enclosure; and a transmission line embedded within the enclosure joins the coupling probe and the external antenna for RF signal transfer. RF transmission signals of the cell phone are radiated from both the internal and the external antennae simultaneously and without mutual interference. | 03-22-2012 |
20130069839 | ISOLATION ENHANCEMENT BETWEEN PLANAR ANTENNA ELEMENTS - An antenna system for creating mutual radiation isolation between planar antenna elements over a narrow band uses field cancellation. Adjacent planar antenna elements are positioned in a common ground plane within a mobile phone repeater station, A tuned slot element is positioned between the antenna elements and coupled to share ground plane current in. order to maximize cancellation and minimize degradation of the radiation of the antenna elements. The dimensions of the toned slot element are adjusted to obtain lambda/2 resonance, whereby, isolation of more than 10 dB is attained between the antenna elements. | 03-21-2013 |
20130072207 | SMART CHANNEL SELECTIVE REPEATER - A system and method for processing signals in a selected channel through a repeater wherein the repeater is dynamically adapted to the channel by receiving channel information from a local cell phone, such information including modulation and channel designation. | 03-21-2013 |
