Abstract: The present invention refers to a method for controlling transmission of an electronically steerable antenna system, wherein the electronically steerable antenna system comprises a signal generator configured to generate electromagnetic waveforms, and an antenna. The antenna comprises an even number of antenna columns symmetrically arranged about a centerline of the antenna and thereby forming two symmetrical antenna halves. Respective antenna column comprises at least one antenna element configured at least for transmitting electromagnetic waves. The electronically steerable antenna system is configured for transmitting at least interrogation signals and ISLS control signals, and the method comprises the method steps of, when transmitting the ISLS control signals: generating an electromagnetic waveform; applying a first transmission phase offset to the electromagnetic waveform, wherein the first transmission phase offset determines the phase offset between each antenna column pair; applying a second transmission phase offset to each antenna column of the second antenna half, wherein the second transmission phase offset of the second antenna half offset is 180 degrees in relation to the first antenna half;and transmitting the generated electromagnetic waveform whereto the first and the second phase offsets have been applied. The present invention also relates to an electronically steerable antenna system configured to execute the method.

Abstract: An antenna system for providing identification functionality comprising a main antenna and an auxiliary antenna, wherein the antennas are configured to at least transmit electromagnetic waves. The antenna system comprises a first channel interface and a second channel interface, a first switch and a transmission input means. The first switch is configured to switch between a first operation mode and a second operation mode. When set in the first operation mode the second channel interface is set to be in connection with the auxiliary antenna and when set in the second operation mode the second channel interface is set to be in connection with the main antenna. If transmission via the first transmission channel is expected the transmission input means is configured to set the first switch in the first operation mode. Thereby the main antenna can be used for transmission of signals both provided via the first and second channel interfaces and when transmission via the first and second channel interfaces simultaneously is required the signal provided via the first channel interface will be transmitted by the main antenna and the signal provided via the second channel interface will be transmitted by the auxiliary antenna.
