摘要： Similar to cell based electronics systems that employ a sea of small unit cells in large scale arrays, such as thin film display monitors or semiconductor memories, an antenna array employs micron to centimeter size antenna pixelate cells that are integrated to form the plate of an antenna. Each row and column of cells in the antenna array may be accessed by digital logic and the RF transmission/reception state of the switchable cell changed. Thus, the antenna plate can be reconfigured and its radiating plate reformed to a specific pattern as an element of a larger array of antennas in wafer scale form.

摘要： Methods and systems are provided for achieving delivery of power wirelessly using a highly beam-formed array of radio frequency (RF) transmitters as a source and a spatially beam-formed array of receivers that collect the impinged RF power and feed a multistage RF to direct current (RF-DC) conversion circuit that, for example, increases output voltage by doubling the voltage at each stage, while power delivery remains constant. One or more embodiments may provide energy wirelessly and—unlike conventional systems where the power flux density may be too low for applications where an energy density (specific energy) on the order of several mega-Joules per kilogram (MJ/Kg) is desired—may provide sufficient power flux density for many practical applications.

摘要： Radar imaging for medical diagnosis addresses the need for non-ionizing and low-cost alternatives to conventional medical diagnosis methods, such as mammography x-ray techniques, which expose patients to ionizing radiation for cancer detection. An ultra wide band (UWB) sensor can produce very fine beams at the V- or W-bands using beam forming techniques developed specifically for wafer scale antenna arrays. The high bandwidth radio waves can penetrate tissue and resolve tissue anomalies with high-resolution. Pseudo-random coding creates a signal that allows the correlating receiver to extract very low energy reflected signals from background noise providing coding gain. An integrated panel of sensor antenna arrays enables rapid scanning of the subject area, such as breast tissue, to detect anomalies by eliminating the need for mechanical scanning (e.g., moving the sensors relative to the subject) because the wafer scale antenna array can instantaneously take the desired topographic picture of the subject area.
