MULTIFREQUENCY INVERTED F-TYPE ANTENNA

摘要

A multifrequency inverted F-type antenna which can receive multifrequency band radio waves without the enlargement of its shape. A cut-out part (12b) is formed in an emission conductor (12) one end of which is connected to a short-circuit plate (13) planted in a ground conductor (11) and which has a feeding point (12a) to form on the emission conductor (12) a first emission conductor (12-1) and a second emission conductor (12-2) which resonate at respective frequency bands different from each other. By this construction, the radio waves of two different frequency bands, i.e. a first frequency band determined by the shape of the first emission conductor (12-1) and a second frequency band determined by the shape of the second emission conductor (12-2), can be received.
