The invention relates to a method and system for the testing of an antenna comprising a plurality of radiating elements, wherein an array of one or more probes is placed in front of the antenna to be tested, and wherein the following steps are performed: acquisition by the array of one or more probes or by the radiating elements of the antenna under test of an RF signal emitted by the antenna under test or by the array of one or more probe (s), back propagation reconstruction of the signal emitted through a computation of the signal received by the various probes of the array of one or more probes or by the radiating elements of the antenna under test, test of the signal thus reconstructed or of parameters thereof to detect a potential defect of the antenna.

Method and system for the testing of an antenna comprising a plurality of radiating elements

The invention concerns a system for simulating electromagnetic environments, including a network of emitting and/or receiving probes to test at least one test antenna, channels for connecting the probes to a channel emulator, a signal emitting unit, a signal receiving unit, one of the units being connected to the emulator. The invention is characterized by a switching device having a first measurement position, in which the device connects the emulator respectively to at least one of the probes via the associated channel and connects the other unit to the test antenna, and a second position for calibrating the channels, in which the switching device connects the emulator to the other unit via the associated channel without passing through the network of probes.

System for simulating electromagnetic environments including a network of a plurality of probes

The invention relates to an antenna that produces a radiation pattern that is axisymmetric about a geometrical axis (X) and exhibits a radiation maximum in a plane perpendicular to the direction of said X axis that includes a feed wire extending along said axis (X) from a first end situated level with a conducting surface forming an earth plane of the antenna to a second end that feeds a set of N radiating strands, N being an integer, characterized in that it also includes at least one earth return rod for the strands, said rod linking one of the radiating strands of the set to the earth plane.
