To provide a technology that can suppress the reduction of an antenna gain while maintaining the quality of the design of the exterior furnishing of the antenna. Provided is an antenna apparatus including: an antenna module that includes a first slot antenna that transmits or receives a first wireless signal, a first feed element that supplies power to the first slot antenna, a second slot antenna that transmits or receives a second wireless signal having a polarization direction orthogonal to a polarization direction of the first wireless signal, and a second feed element that supplies power to the second slot antenna; and a metal plate that includes a first slot, and a second slot a longitudinal direction of which is orthogonal to a longitudinal direction of the first slot.

Antenna apparatus

To optimize space efficiency in mounting a plurality of antennas compatible with different frequencies. According to the present disclosure, provided is an antenna device including a first antenna that operates at a first frequency, and a second antenna that is provided adjacent to the first antenna, operates at a second frequency lower than the first frequency, and has a ground potential connected to a grounding wire provided at the first antenna.

Antenna device

[Problem] To prevent radiation waves from being reflected inside a casing when a plurality of antennas compatible with different frequencies are mounted. [Solution] According to the present disclosure, provided is an antenna apparatus including a first antenna that operates at a first frequency, and a second antenna that is arranged on an outer side of a casing relative to the first antenna, that operates at a second frequency lower than the first frequency, and that includes an opening in a radiation direction of the first antenna.
