Abstract
An antenna apparatus according to the invention comprises an inverse F-element provided on a grounding conductor. The inverse F-element is constituted by an L-shaped radiating conductor and a short-circuiting conductor. The radiating conductor is constituted by a vertical portion vertically extending from a feeding point provided maintaining a gap with respect to the grounding conductor, and a horizontal portion extending in parallel with the grounding conductor from an upper end of the vertical portion. The vertical portion of the radiating conductor is of a meandering shape.
