Title:
ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2022185355
Kind Code:
A
Abstract:
To provide an antenna device which can be widely applied to a plurality of frequency bands and constitute a plurality of antennas in the same frequency band.SOLUTION: An antenna device comprises a plurality of dipole antenna groups and a fourth dipole antenna which are supplied with power from a power supply part of a bottom board via a power supply line. The dipole antenna group comprises: a first dipole antenna; a second dipole antenna; and a third dipole antenna which is applied to a third frequency band. The first dipole antenna is provided on an end side of a bottom board with respect to the second dipole antenna. The second dipole antenna is provided on an end side of the bottom board with respect to the third dipole antenna. An end of an antenna element of the first dipole antenna is bent to the second dipole antenna side. An end of the antenna element of the second dipole antenna is bent to the third dipole antenna side. The fourth dipole antenna is arranged among the dipole antenna groups. The fourth dipole antenna is applied to the third frequency band.SELECTED DRAWING: Figure 1
