Abstract
An antenna device which includes a plurality of antennas in a common case and is capable of achieving downsizing while suppressing a decrease of an antenna gain, is provided. An antenna device includes a TEL antenna and a capacity loaded element in a common case. The capacity loaded element is located above the TEL antenna. A length of the capacity loaded element is a positive integer multiple of one-half a wavelength of a PCS band. The TEL antenna is arranged so as to avoid a voltage maximum point of a standing wave, of the PCS band, generated in the capacity loaded element.
Claims8
An antenna device comprising:
- a first antenna;
- and
- a second antenna including a capacitively loaded element which is located above the first antenna and a helical element which is electrically connected with the capacitively loaded element in a series connection,
- wherein at least a part of the first antenna overlaps the capacitively loaded element in a side view of the antenna device,
- wherein the capacitively loaded element is made of a conductive plate, and
- wherein a feeding point of the first antenna and a feeding point of the second antenna are different from each other.
