Abstract:
A chip antenna, comprising:a first generally planar sheet having a plurality of spaced, first conductors formed on one major surface thereof,a second generally planar sheet having a plurality of spaced second conductors formed on one major surface thereof;at least one generally planar additional sheet located between said first and second generally planar sheets;said first, second and at least one generally planar additional sheet being laminated together to form an elongated structure wherein respective pairs of first and second conductors are coupled to one another through said at least one generally planar additional sheet to form respective spiral loops of a spiral antenna so that a central axis of said spiral antenna extends generally parallel to a longitudinal direction of said elongated structure;each of said sheets being formed of a material having a permeability of 1<u<7; anda feeding terminal coupled to one end of said spiral antenna so that said chip antenna forms a mono-pole antenna.
