<p>The invention concerns a portable receiver comprising two antennae (10, 20) which are designed to receive an external electromagnetic signal in a given frequency range, and which are oriented along different axes. The receiver also comprises two phase-shifting circuits (12, 22) connected each to an antenna, and multiplexing means (24) whereto are connected in input said phase-shifting circuits and in output a receiver unit receiving the external phase-shifted electromagnetic signal. Additionally, is provided between at least one of the phase-shifting circuits (12) and the antenna (10) connected to said circuit, correcting means (Rcor, Ccor) which are dependent on the phase-shifting means, on said multiplexing means and on the antennae. The correction means are designed to supply in output of the phase-shifting circuits first and second electric signals phase-shifted by an angle π/2 relative to one another and substantially equal in amplitude.</p> |
