Abstract
An antenna apparatus and a radio communication apparatus are capable of separately controlling a resonance frequency in a basic mode and a resonance frequency in a higher mode and have a wide bandwidth in which the resonance frequency in the basic mode is variable. The antenna apparatus includes a feeding electrode, a loop-shaped radiation electrode, a capacitance portion, and inductorsand. The capacitance portionis formed by a gap between an open endof the loop-shaped radiation electrodeand the feeding electrode. The inductoris disposed at a position where a large current is obtained in the basic mode and a small current is obtained in the higher mode. The inductoris disposed at a position where a large current is obtained in the higher mode and a small current is obtained in the basic mode.
