Abstract: An antenna that provides a radiation pattern that is tilted relative to the perpendicular to the plane of the antenna is provided. The antenna may be located on an angled surface, but have its tilted beam reach maximum gain at its zenith. In alternative embodiments, the antenna may be substantially transparent or translucent allowing placement on a surface without blocking viewing through the surface.

Abstract: A monitoring/calibrating system is provided based on the amplitude and/or phase of electric and/or magnetic fields measurements. In transmitter mode of AUT, one or more probe sets are placed very close to the AUT around the radiation aperture of AUT to prevent probes effects on the AUT performance. For each amplitude/phase state of AUT controller, the near field data are measured and compared with a previously stored dataset. A successive method can reduce the error by changing the amplitude/phase of AUT controller. Moreover, a machine learning method can be used to classify the errors in near field data, errors in amplitude/phase of AUT controller, and automatically tuning the AUT controller. In receiver mode of AUT, the system is the same but the probe sets are working as transmitters to make a known near field around the AUT.

Abstract: A wireless sensor is provided for use in near-to-zero or zero-power consumption applications. The sensor includes a sensing circuit, a modulator connected to the sensing circuit and configured to modulate an input signal using variations in input impedance produced by the sensing circuit to produce a modulated output signal, and a transmitting element such as an antenna to transmit the modulated output signal to a receiver. In some implementations, the sensor includes a pilot sequence generator that may be powered by a received signal from a transmitting node. The input signal is thus modulated by both pilot data and the input impedance. The input signal may be received from the transmitting node. Alternatively, a power source may be provided in the wireless sensor for generating the input signal and/or pilot data.

Abstract: A computer-implemented method for adaptive near-field data acquisition during a sampling process; it includes measuring at least one of an amplitude and phase of a field using one or more probes, wherein the measuring is performed at a plurality of points; selecting, for each point of the plurality of points, a set of neighboring points; calculating a field variation to determine the presence of a strongly varying near-field pattern; for each location corresponding to each point of the plurality of points where a varying near-field pattern is determined after the calculating of the field variation, inserting one or more new points; and for each of said one or more new points, calculating a field variation to obtain a higher near-field resolution for said each location where a near-field variation is determined.
