    Abstract: The invention relates to a method and a system for providing current from a DC power supply to pulsed loads in an array. The array comprises at least two electronic units.Each electronic unit comprises a regulator connected to an energy storage,to a pulsed load and to a charge control unit. The charge control unit is arranged to control the supply of DC current to the pulsed load connected to the electronic unit. The method comprises: selecting a pulse load pattern for the pulsed loads, selecting a charge control sequence by a control system connected to the electronic units and the DC power supply, starting the selected charge control sequence, starting the pulse load pattern, providing DC current from the DC power supply to each electronic unit at different times according to the selected charge control sequence set by the charge control unit.

    Abstract: The present disclosure relates to a notch antenna structure (1) comprising a plurality of notch antenna elements (2) arranged in at least a first row (R). Each notch antenna element (2) comprises a base portion (3) having first and second opposing surfaces (4, 5), a first electrically conductive body (6) and an adjacent second electrically conductive body (7), the electrically conductive bodies (6, 7) extending vertically from the first surface (4), forming an integral structure, a tapering gap (8) between the two electrically conductive bodies (6, 7). The notch antenna structure comprises a bottom plane (9) for receiving the second surface (5) of the plurality of notch antenna elements (2) and the first electrically conductive body (6) comprises a leg portion (10) having a feed arrangement proximate to the tapering gap (8), the feed arrangement comprising a feed point (11).
