Abstract

Abstract The present invention is directed to provide a compact chip antenna (10) for mobile communication comprising a base member (11) which comprises either of a material having a dielectric constant ε of 1 < ε < 130 or a material having a relative permeability µ of 1 < µ < 7, at least one conductor (12) formed on the surface of the base member (11) and/or inside the base member (11), and at least one feeding terminal provided on the surface of the base member (11) for applying a voltage to the conductor (12). The conductor (12) comprises a metal mainly containing any one of copper, nickel, silver, palladium, platinum, or gold.
