<p>The invention provides a method to minimise the influence of interference sources by control of the Signal to Noise/interference Ratio, SNR, of a wideband antenna system connected to an electronic system. The wideband antenna system comprises at least one array of at least two antenna elements/sub arrays. The SNR control comprises establishing of cancellation directions for interfering frequencies in the antenna pattern in the direction of interference sources. The wideband antenna system is operational over a system bandwidth and operates with an instantaneous bandwidth B. Estimation of interference source parameters is performed in an evaluation process. The invention also provides a wideband antenna system implementing the method.</p> |
