Abstract

This paper shows how the tilt angle associated with a linearly polarized signal can be obtained by direct homodyne detection using a broad-band dual-port travelling-wave circularly polarized antenna. The resulting sensor would find applications in systems where polarization shift due to multipath reflections occurs and requires quantification and/or compensation. The operation of the sensor is demonstrated at 1.6-2.4 GHz and a simple analytical model given that establishes the principle of operation.
