Abstract
An antenna includes a parallel resonant circuit disposed in a non-ground region. The parallel resonant circuit includes a parallel radiation electrode pattern that is patterned in the non-ground region and a surface mount antenna component. The parallel radiation electrode pattern is connected in parallel to the surface mount antenna component. The parallel radiation electrode pattern is arranged in a loop so as to occupy the majority of the non-ground region and defines an inductor of the parallel resonant circuit. A pair of electrodes of the surface mount antenna component defines a capacitor having a capacitance corresponding to a distance between the pair of electrodes.
