Abstract: An apparatus that includes two non-coinciding arrangements disposed in an two axes Cartesian coordinate system such that each arrangement having a non-zero projection on a respective axis from among the two axes. Each one of the arrangements includes a pair of oppositely directed, spaced apart, co-axial radiating-capable elements, each of the elements being hollow with internal space, and being slotted throughout its entire extent. A first circuitry coupled to the arrangement and being configured to sense an electric field projection along the axis and to convey it to a first feeding terminal. A second circuitry coupled to a slot of the arrangement and being configured to sense a magnetic field's projection along said axis and to convey it to a first feeding terminal.

Abstract: A direction-finding antenna system is described. The direction-finding antenna system comprises a plurality of tapered dipole antenna elements arranged in circular array around a central axis. Each tapered dipole antenna element comprises a pair of rectangular elongated antenna elements mounted radially from said central axis and configured to be curved such that a distance between said pair of rectangular elongated antenna elements is larger at periphery of the system with respect to center thereof.

Abstract: A method and system are presented for determining properties of an electromagnetic waveform. The method comprises: providing measured parametric EM field data indicative of measured vector components of electric and magnetic fields of an EM waveform measured in at least one instance of time; providing reference data indicative of a plurality of reference data sets, each data set comprising: a reference steering vector parameters indicative of a certain respective direction of arrival (DOA), and a corresponding parametric EM field reference data including reference vector components of an electric and magnetic field pertaining to a wavefront propagating with the DOA of the corresponding reference steering vector parameters; determining a matching score between the measured parametric EM field data and the parametric EM field reference data of one or more of the reference data sets; and in case the matching score of a certain reference data set complies with a certain threshold condition, determining that said measured parametric EM field data corresponds to said EM waveform having a single EM wavefront thereby enabling to discriminate between measured EM waveforms having a single wavefront and measured EM waveforms having multiple wavefronts.

Abstract: The present invention relates to an antenna device including an integrated matching circuit being implemented by at least one controllable capacitor for a number of frequencies. The at least one controllable resonating capacitor determines a resonance frequency of the antenna device. An object of the invention is to provide a compact antenna device which can obtain a desired matching characteristic without using a separate matching circuit which limits miniaturization of the antenna system as a whole and forms a factor of limiting the efficiency of the antenna and raising cost when the antenna is incorporated into the terminal.

Abstract: There is provided an apparatus, including: an arrangement that includes at least one pair of oppositely directed, spaced apart, radiating-capable elements along a common axis, each of said elements being hollow with internal space, and being slotted throughout its entire extent; a first circuitry coupled to said arrangement and being configured to sense an electric field projection along said axis and to convey it to a first feeding terminal; and a second circuitry coupled to at least one slot of said arrangement configured to sense a magnetic field's projection along said axis and to convey it to a first feeding terminal. The apparatus being further configured to resolve a polarization vector of incoming wavefront propagating in an orthogonal direction to said common axis based on at least said sensed electric field projection and said magnetic field projection.
