Abstract:
1. A planar inverted F antenna comprising: a grounding element that defines a grounding surface; a first radiation element that is spaced apart from the grounding surface and extends in a same direction as a direction in which grounding element extends; a first short-circuit element that short-circuits the grounding element and the first radiation element and is provided at an end of the first radiation element; a second short-circuit element that short-circuits the grounding element and the first radiation element and is provided spaced apart from the first short-circuit element; a power supply section that is provided at the first short-circuit element or the second short-circuit element; and a second radiation element that is provided parallel to the grounding surface and extending partially with respect to the first radiation element in a longitudinal direction, the second radiation element being provided so as to substantially increase a width of the first radiation element in the vicinity of the power supply section, the second radiation element whose length in a width direction of the first radiation element is equal to or shorter than one-fifteenth of a wavelength corresponding to an operating frequency.
