Phase Noise Improvement in a Loop Configuration of Oscillating Antennas

Laurent Dussopt and Jean-Marc Laheurte

Page 111.

Abstract:

Phase noise in a four-element array of oscillating antennas is analyzed for a loop configuration and a unilateral coupling topology. It is demonstrated that this structure, basically designed for circular polarization (CP) applications, also yields a 75% reduction of the near-carrier phase noise compared to a single oscillator. Experimental validation is made at 4 GHz. For this structure, deviation of the coupling phase from its nominal value has no influence on the phase noise performance.
