Abstract:
1. A mobile terminal, comprising: a printed circuit board having first and second opposite sides and having a reference voltage conductor therein; an antenna coupled to the first side of the printed circuit board; and a parasitic resonator having first and second couplings to the second side of the printed circuit board wherein the printed circuit board and the first and second opposite sides thereof are between the antenna and the parasitic resonator, wherein the first coupling to the printed circuit board provides a first impedance between the parasitic resonator and the reference voltage conductor, wherein the second coupling to the printed circuit board provides a second impedance between the resonator and the reference voltage conductor wherein the first and second impedances are different, and wherein the second coupling provides a capacitance between the reference voltage conductor and the parasitic resonator that is greater than a capacitance provided by the first coupling between the reference voltage conductor and the parasitic resonator.
