Abstract: An elementary microstrip antenna includes a stack of layers, stacked in a direction z, the stack comprising: a first conductive radiating element of disc shape having a first centre, an axis in the direction z and passing through the first centre being called the central axis; a coupling assembly configured to couple an exciting device and the first radiating element, the coupling assembly comprising: a first slot comprising a centre called the slot centre located on the central axis; a second slot comprising a centre coincident with the slot centre, and substantially perpendicular to the first slot, the first and second slots each comprising circularly arcuate ends on the same circle centred on the slot centre; the slots and the stacked layers being configured so that a transverse footprint of the elementary antenna is disc-shaped.

Abstract: The invention relates to a device for protecting at least one active component of an electronic module, able to receive a microwave electromagnetic signal as input and to provide a microwave electromagnetic signal to said at least one active component. This device includes a delay module able to apply a predetermined delay time to the microwave electromagnetic input signal, connected in parallel with a switch-triggering device able to compare a power level of the microwave electromagnetic input signal to a power threshold and to command switching by a switch connected at the output of the delay module, an output of said switch providing the microwave electromagnetic signal to said at least one active component, the predetermined delay time being such that the switching is done before the arrival of the microwave electromagnetic output signal from the delay module.
