摘要： 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.

摘要： The present invention relates to an antenna system including at least two antenna modules operable for transmitting and/or receiving radiation in certain common frequency band. The at least two antenna modules are collinearly arranged along a common axis so as to provide low gain along the axis, and are spaced apart from one another along this axis by a distance of at least a few nominal wavelengths of the common frequency band. Each two locally adjacent antenna modules of the at least two antenna modules operate with substantially mutually orthogonal polarizations of radiation, thereby suppressing electromagnetic coupling between the antenna modules in the common frequency band.

摘要： 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.

摘要： 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.
