    摘要: The invention relates to a monopole antenna with a radiating element mounted onto a base by means of a mast, of which the radiating element is formed from two conductive strands, in U, the length L of each strand being chosen such that ¼ λg≦L≦½ λg, λg being the wavelength in a strand at a central radiation frequency F0.

    摘要: The method of improving the carrier-to-noise ratio for a receiver with diversity, and the associated device, consists, after extracting, by phase shifting, the noise component of the signals to be demodulated, in optimizing the cancellation of the useful component via a feedback loop acting on the phase shifter and in summing the noise component in phase and in phase opposition with these signals to improve the carrier-to-noise ratio.
