ABSTRACT:
An antenna adaptable to a plurality of frequencies is comprised of a first element that is connected to a feeding point (feeding portion) for operation and a second element that is connected to a grounding point (grounding portion) in proximity to the first element to be operated by coupling feeding with the first element and is configured to be operated at either or both of a first frequency and a second frequency higher than the first frequency.
