Abstract
A slit () is formed between a feed point and GND point of an inverted-F antenna to make the points electrically distant from each other, and at least three antenna elements (, and) are formed. The at least three antenna elements (, and) generate at least three resonance points. An antenna radiating plate () projects outwardly so that at least a major part thereof does not face a ground plate (). Therefore, a multi-band antenna device capable of achieving a wider bandwidth without using a parasitic element, and a communication terminal apparatus are provided.
