1. An antenna comprising:
- a mount board having a non-ground region;
a parallel resonant circuit provided in the non-ground region, the parallel resonant circuit including a surface mount antenna component including a substrate and at least a pair of electrodes arranged on a surface of the substrate so as to face each other with a predetermined distance therebetween to define a capacitor, and a parallel radiation electrode pattern having an inductor and a feed electrode, the parallel radiation electrode pattern being connected in parallel to the capacitor; and
a first lumped-constant inductor connected to or included in the parallel resonant circuit.

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.
