Abstract
The present invention relates to an antenna device comprising an antenna part having a patch with several edges, a first transmit path connected to a first connection port at a first edge of the patch, and a second transmit path connected to a second connection port at the first edge of the patch. The first and second connection ports are located at a distance from each other along the first edge, and a first transmitter and a second transmitter are connected to the antenna part. The first transmit path comprises a first signal combiner connected to the first and second transmitters and to the first connection port. The second transmit path comprises a second signal combiner connected to the first and second transmitters and to the second connection port. The first signal combiner is arranged to generate a difference between signals originating from the first and second transmitters. The second signal combiner is arranged to generate a sum of the signals originated from the first and second transmitters. Thereby, it is possible to simultaneously transmit two different signals. A method for transmitting a radio frequency signal by means of the device is provided as well.
