Abstract: A system for generating, transmitting and distributing electrical energy has a generator of electric energy, a convertor for converting the generated electric energy to microwaves, a transmitter for wirelessly transmitting the generated microwaves over a space without a microwave connection, a receiver for receiving the transmitted microwaves, and a converter for converting the received microwaves into electric energy to be supplied to consumers.

Abstract: A method and device for adaptive performance optimization of wireless receivers operating in dynamic electromagnetic environments are disclosed. The wireless receiver measures the frequency and amplitude of all interference signals that can affect the quality of the desired received signal. Based on the interference signals, the wireless receiver estimates the effects of the interference signals on the desired received signal and mitigates the influence of the interference signals by totally suppressing or at least significantly reducing the interference signals through the use of adjustable components along the receiving chain. By dynamically adapting the receiver's sensitivity and selectivity, the most optimal conditions for receiving the desired signal at each moment are provided.

Abstract: A surface antenna with a single radiation element, which comprises (a) a power source with first and second poles; (b) a phase shifting element, inserted to the path of one of the poles of the power source in such a manner that the phase shifting device shifts the phase of a first signal propagating through said pole such that the shifted phase of the first signal will be essentially identical to the phase of a second signal propagating through the other pole. The shifted first signal is added to the second signal with essentially the same phase of second signal, whenever both poles are connected together to form a single-wire, through which the resulting added signal propagates.

Abstract: A system that includes a phase shifter and a radiating element of an electrical circuit; wherein the phase shifter is arranged to: (a) receive, from a first lead of a feed line, a first signal that is a radio frequency (RF) signal; (b) delay the first RF signal by about 180 degrees to provide a delayed signal; and (c) provide the delayed signal to a first feeding point of the radiating element; wherein the radiating element further comprises a second feeding point that is arranged to receive from a second lead of the lead line a second signal that is a RF signal; wherein the delayed signal and the second signal are substantially in phase. The system can include or be an improved MB antenna.
