Antenna arrangement, transceiver arrangement, communication system, actuator device, and method for operating an antenna arrangement

An antenna arrangement that defines a main radiation direction, the antenna arrangement comprising:

• two more antennas each having a respective feed-in point;
• a printed circuit board that has a side area, wherein the two or more antennas are connected to the printed circuit board at the side area thereof;
• and
• an attenuation arrangement on the side area of the printed circuit board, wherein
• the attenuation arrangement has a first attenuation unit that defines an access opening within which the two or more antennas are jointly arranged;
• a central axis of the defined access opening runs along the main radiation direction of the antenna arrangement;
• a common transmit antenna group among the two or more antennas comprised of a first transmit antenna and a second transmit antenna;
• a common receive antenna group among the two or more antennas comprised of a first receive antenna and a second receive antenna;
• the first transmit antenna, the second transmit antenna, the first receive antenna and the second receive antenna are jointly arranged inside the attenuation arrangement;
• a first balun in the common transmit antenna group, the first balun having a symmetric connection and having an asymmetric connection;
• and
• a second balun in the common receive antenna group, the second balun having a symmetric connection and having an asymmetric connection;
• wherein
• the first transmit antenna is connected to a first symmetric connection of the first balun and the second transmit antenna is connected to a second symmetric connection of the first balun;
• the first receive antenna is connected to a first symmetric connection of the second balun and the second receive antenna is connected to a second symmetric connection of the second balun;
• the asymmetric connection of the first balun is connectable to a transmit signal path of a transceiver arrangement;
• and
• the asymmetric connection of the second balun is connectable to a receive signal path of the transceiver arrangement independent from the transmit signal path.

A communication system comprising:

• a first transceiver arrangement;
• and
• a second transceiver arrangement;
• wherein
• each of the first and the second transceiver arrangements has an antenna arrangement for providing wireless signal transmission between the first and the second transceiver arrangements, each antenna arrangement defining a main radiation direction, and each antenna arrangement having,
• two or more antennas each having a respective feed-in point;
• a printed circuit board that has a side area, wherein the two or more antennas are connected to the printed circuit board at the side area thereof;
• and
• an attenuation arrangement on the side area of the printed circuit board,
• wherein
• the attenuation arrangement has a first attenuation unit that defines an access opening within which the two or more antennas are jointly arranged;
• and
• a central axis of the defined access opening runs along the main radiation direction of the antenna arrangement.
