Abstract
An electronic device includes a first reception antenna having a directivity in a first direction, and a second reception antenna having a directivity in a second direction different from the first direction. As a polarization direction of a radio wave received by the first reception antenna becomes closer to a first polarization direction, a gain of reception by the first reception antenna becomes greater. As a polarization direction of a radio wave received by the second reception antenna becomes closer to a second polarization direction different from the first polarization direction, a gain of reception by the second reception antenna becomes greater.

An electronic device comprising:
- a first reception antenna having a directivity in a first direction;
- and
- a second reception antenna having a directivity in a second direction different from the first direction, wherein as a polarization direction of a radio wave received by the first reception antenna becomes closer to a first polarization direction, a gain of reception by the first reception antenna becomes greater, and
- as a polarization direction of a radio wave received by the second reception antenna becomes closer to a second polarization direction different from the first polarization direction, a gain of reception by the second reception antenna becomes greater.
An electronic device comprising:
- a first transmission antenna configured to transmit, using first polarization, a radio wave having a directivity in a first direction;
- and
- a second transmission antenna configured to transmit, using second polarization, a radio wave having a directivity in a second direction different from the first direction, wherein
- the first transmission antenna transmits a signal in the first polarization direction by means of a first feeding layout, and
- the second transmission antenna transmits a signal in the second polarization direction by means of a second feeding layout.
A transmitting-and-receiving system comprising:
- a transmitter including transmission antennas;
- and
- a receiver including reception antennas,
- the transmitter including
- a first transmission antenna configured to transmit, using first polarization, a radio wave having a directivity in a first direction, and
- a second transmission antenna configured to transmit, using second polarization, a radio wave having a directivity in a second direction different from the first direction,
- the receiver including
- a first reception antenna having a directivity in the first direction, and
- a second reception antenna having a directivity in the second direction, wherein
- as a polarization direction of a radio wave received by the first reception antenna becomes closer to a first polarization direction, a gain of reception by the first reception antenna becomes greater, and
- as a polarization direction of a radio wave received by the second reception antenna becomes closer to a second polarization direction different from the first polarization direction, a gain of reception by the second reception antenna becomes greater.
