Compact 3D direction finding and polarization resolving

A method for determining polarization vector of an electro-magnetic (EM) wavefront, comprising

• (i) providing 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 a second circuitry coupled to at least one slot of said arrangement
• (ii) utilizing said first circuitry for sensing an electric field projection along said common axis and to convey it to a first feeding terminal;
• (iii) utilizing said second circuitry for sensing a magnetic field's projection along said common axis and to convey it to a first feeding terminal;
• and
• (iv) resolving the polarization vector of the wavefront propagating in an orthogonal direction to said common axis based on at least said sensed electric field projection and said magnetic field projection.
