ABSTRACT:
A multi-band inverted-F antenna includes a first high frequency leg; a low frequency leg; a feed, from which the first high frequency leg and the low part are extending; a second high frequency leg, extending along a lengthwise direction of the first high frequency leg from one end of the feed pin a plane orthogonal to that of the first high frequency leg; a regulating part; and a ground, having one end coupled to the feed and a further end coupled to the regulating part. From the surface currents flowing from the feed through the first high frequency leg and the second high frequency leg, the antenna is provided with a multiply widened high-frequency band. Moreover, from the surface currents flowing from the feed, through the regulating part, the lower surface of the regulating part, the lower surface of the first high frequency leg, and the lower surface of the second frequency part, the resistances of the respective first and second high frequency legs of the antenna are regulated to be matched to each other, so that the high frequency leg as a whole of the antenna is operable in a wide-area band.
