Summary:PROBLEM TO BE SOLVED: To provide an antenna structure for a wide frequency band without lowering antenna efficiency. SOLUTION: The groove (103) provided in the planar radiator (110) of an antenna is used to generate the resonance of various frequency ranges, and enables the generation of two or more separate frequency ranges and at least one frequency range including as its subject the band width of some mobile communication systems used. The groove (103) is provided in the planar radiator (110), and is provided such that at least one part of the groove is positioned between a power supply point (101) and a grounding point (102).
