Abstract:
Provided is an antenna device provided with a plurality of antennas in a common case and capable of achieving downsizing while suppressing a reduction in antenna gain.
An antenna device 1 is provided with a TEL antenna 2 and a capacity loaded element 3 in a common case. The capacity loaded element 3 is located above the TEL antenna 2. The length of the capacity loaded element 3 is a natural number multiple of a half of a PCS-band wavelength. The TEL antenna 2 is disposed so as to avoid a maximum voltage point of a PCS-band standing wave generated in the capacity loaded element 3.
