A passively re-radiating cell phone sleeve assembly capable of receiving a nested cell phone provides signal boosting capabilities. Signal boosting is enabled by use of an additional antenna, a pass-through repeater, dual antenna isolation capability and other features.

Sleeve with electronic extensions for a cell phone

A device includes (a) a plurality of radio frequency (RF) switches, each operable with a plurality of frequency bands; an RF coupling device; and a processor programmed to selectively control operation of the plurality of RF switches based on an uplink signal from an electronic communication device electromagnetically coupled with the RF coupling device. The processor is programmed to selectively control operation of the plurality of RF switches by causing each of the RF switches to lock on a particular frequency band of the plurality of frequency bands corresponding to a frequency of the uplink signal from the electronic communication device.

Automatic RF antenna switching for an electronic communication device

A passively re-radiating cell phone sleeve assembly capable of receiving a nested cell phone provides signal boosting capabilities and provides a radar enablement. Signal boosting is enabled by use of an additional antenna, a pass-through repeater, dual antenna isolation capability and other features.

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.

Isolation enhancement between planar antenna elements

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.

Smart channel selective repeater

A hand-held apparatus has a Doppler radar secured within one wall of a phone sleeve. A phone may be placed within the sleeve and in signal communication with the radar via a connector molded in the sleeve. In operation, an RF signal may be directed toward a distant moving target and a bounce signal received. The speed of the target is calculated from the Doppler frequency shift and displayed by the phone to the user.

Combination hand-held phone and radar system

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.
