    摘要: The present invention provides an antenna device having a simple configuration for multiband operation. The antenna device is provided with: a first antenna element which is provided in a first layer of a multi-layer substrate and has a first frequency band; a second antenna element which is provided in a second layer of the multi-layer substrate different from the first layer, and has a second frequency band lower than the first frequency band; a ground substrate; a first feeding line path extending from the first antenna element toward the ground substrate; a second feeding line path extending from the second antenna element toward the ground substrate; and a filter connecting the second antenna element and the around substrate, the filter passing a signal of the first frequency band and blocking a signal of the second frequency band.

    摘要: 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.
