Abstract
Provided is an antenna device with a simple configuration, said antenna device supporting a plurality of frequency bands. An antenna device according to the present invention is provided with: at least one first radiation element that has a resonant frequency in a first frequency band; at least one second radiation element; and a connection line for connecting the first radiation element and the second radiation element. The line length formed of the first radiation element, the connection line, and the second radiation element is set to a length so as to have a resonant frequency in a second frequency band lower than the first frequency band.
Claims15
An antenna apparatus, comprising:
- at least one first radiation element having a resonance frequency in a first frequency band;
- at least one second radiation element;
- a connection line connecting between the first radiation element and the second radiation element,
- wherein a line length formed by the first radiation element, the connection line, and the second radiation element is set to a length so as to have a resonance frequency in a second frequency band lower than the first frequency band.
An apparatus, comprising:
- circuitry, which in operation, controls:
- at least one first radiation element having a resonance frequency in a first frequency band;
- and
- at least one second radiation element, wherein the first radiation element and the second radiation element are connected by a connection line;
- and
- a transmitter, which in operation, radiates radio waves generated by the circuitry,
- wherein a line length formed by the first radiation element, the connection line, and the second radiation element is set to a length so as to have a resonance frequency in a second frequency band lower than the first frequency band.
A method, comprising:
- controlling
- at least one first radiation element having a resonance frequency in a first frequency band;
- and
- at least one second radiation element, wherein the first radiation element and the second radiation element are connected by a connection line;
- radiating radio waves generated by the at least one first radiation element and the at least one second radiation element,
- wherein a line length formed by the first radiation element, the connection line, and the second radiation element is set to a length so as to have a resonance frequency in a second frequency band lower than the first frequency band.
