Abstract:
A density-optimized short-range wireless communications antenna system has a first radiating element, a second radiating element, and a radio frequency transmitter that generates a radio frequency signal. A power divider has an input port connected to the radio frequency transmitter, a first output port, and a second output port connected to the second radiating element, and a signal power of the radio frequency signal is split between the first output port the second output port. A phase shifter is connected to the first output port of the power divider and to the first radiating element, with a phase of the first split radio frequency signal being shifted by a prescribed degree relative to the second split radio frequency signal.

Claim (Index 10):
A short-range wireless communications antenna array for transmitting to one or more receiving personal electronic devices within a single area occupied by a passenger, the wireless communications antenna comprising:\n a first antenna element defined by a first radiation pattern; and a second antenna element defined by a second radiation pattern; wherein the first antenna element and the second antenna element together define a directional array having a radiation pattern including a main lobe oriented toward a receptor direction, one or more sidelobes, and a backlobe, with the first antenna element being fed a first split of a radio frequency signal and the second antenna element being fed a second split of the radio frequency signal phase shifted from the first split of the radio frequency signal, radio frequency signals from each of the first antenna element and the second antenna element inducing a destructive interference minimizing the sidelobes and backlobes in the radiation pattern of the directional array and inducing a constructive interference maximizing the main lobe in the radiation pattern of the directional array within the single area occupied by the passenger without interference to adjacent areas for personal electronic devices of other passengers, based at least in part upon a tuning of a phase shift between the first split and the second split of the radio frequency signal and a minimal power output level evaluated to maintain a communication link to the one or more receiving personal electronic devices.
