Abstract
An integrated antenna module to be applied to an in-vehicle system includes an antenna element group that is mounted on a vehicle and is formed of a plurality of antenna elements, and the antenna element group constitutes a plurality of antennas capable of transmitting or receiving a plurality of electromagnetic waves by combining the plurality of antenna elements.
Claims20
An integrated antenna module comprising:
- an antenna element group that is mounted on a vehicle and is formed of a plurality of antenna elements, wherein
- the antenna element group constitutes a plurality of antennas capable of transmitting or receiving a plurality of electromagnetic waves by combining the plurality of antenna elements,
- the antenna element group is configured to include a switching unit,
- the switching unit is configured to operate the antenna element group in a plurality of different transmission/reception modes by switching a mutual connection state of the plurality of antenna elements,
- the antenna element group is configured to operate in an omnidirectional antenna mode in which the plurality of antenna elements are set to an aggregated state and aggregates electromagnetic waves received by each antenna constituted by each antenna element in to one signal and a directional antenna mode in which the plurality of antenna elements are set to an independent state and independent electromagnetic waves received by each antenna constituted by each antenna element to one signal by one signal, as the plurality of different transmission/reception modes, and
- in the omnidirectional antenna mode, a signal of the antenna having an excellent reception condition is preferentially used or signals are synthesized to remove noise for signals based on same electromagnetic waves from a same transmission/reception target received by the plurality of antennas.

An integrated antenna module comprising:
- an antenna element group that is mounted on a vehicle and is formed of a plurality of antenna elements;
- a communication control module that controls an operation of the antenna element group;
- a housing to which at least some of the plurality of antenna elements and at least a part of the communication control module are assembled;
- and
- an optical signal transmission unit that is interposed between the plurality of antenna elements and the communication control module, converts an electric signal into an optical signal and transmits the converted optical signal, and converts the transmitted optical signal into an electric signal, wherein
- the antenna element group constitutes a plurality of antennas capable of transmitting or receiving a plurality of electromagnetic waves by combining the plurality of antenna elements.
