摘要： 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 2, a loop-shaped radiation electrode 3, a capacitance portion 4, and inductors 5 and 6. The capacitance portion 4 is formed by a gap between an open end 3a of the loop-shaped radiation electrode 3 and the feeding electrode 2. The inductor 5 is 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 inductor 6 is disposed at a position where a large current is obtained in the higher mode and a small current is obtained in the basic mode.

摘要： A radiation electrode is formed on a substrate of a surface mount antenna. One end of the radiation electrode forms a ground connection portion connected to ground, and the other end of the radiation electrode forms an open end. A ground connection electrode for connecting the open end of the radiation electrode to ground via a capacitance is provided on the substrate. No feeding electrode for feeding power to the radiation electrode is provided on the substrate. This surface mount antenna is mounted on a non-ground region (a region on which a ground electrode is not formed) of a board so as to constitute an antenna structure. On the board of the antenna structure, a feeding electrode for capacitively feeding power to the radiation electrode is provided at a position between the ground connection portion and the open end.

摘要： A compact and thin antenna device can be mounted in a small area of a substrate and has a multiband capability adaptable to various applications. The antenna device includes a chip antenna, an antenna element, and a chip antenna. The chip antenna is produced by forming a radiation electrode on the surface of a dielectric base, and mounting a frequency variable circuit on the radiation electrode. Thus, it becomes possible to obtain a resonant frequency f1 of the chip antenna and further to vary the resonant frequency f1. The antenna element is produced by adding an auxiliary element to an additional radiation electrode for the chip antenna. The chip antenna includes a radiation electrode on a dielectric base and a conductive pattern. Thus, a resonant frequency f2 and a resonant frequency f3 of the antenna element and the chip antenna, respectively, can be obtained.
