Carrier Tracking using Extended Kalman Filters for GNSS Synthetic Aperture Processing with a Rotating Antenna

Pierre-André Farine, Cyril Botteron, Miguel Angel Ribot Sanfelix, Joaquin Cabeza de Pablo

A single GNSS antenna moving along a known trajectory can be used to synthesize a virtual array in order to apply spatial diversity techniques, e.g. beamforming. With these techniques, referred as synthetic aperture (SA) techniques, the receiver can mitiga ...

Wideband Omnidirectional Planar Antenna with Vertical Polarization

Juan Ramon Mosig, Lei Wang

In this paper we propose a circular leaky wave-antenna with omnidirectional radiation in the H-plane. The design utilizes double-layered strips to create an end-fire antenna. A linear tapering of the stripes in the design endows the antenna with a 27% impe ...

GNSS Multipath Estimation and Mitigation Using a Rotating Antenna

Pierre-André Farine, Cyril Botteron, Miguel Angel Ribot Sanfelix, Joaquin Cabeza de Pablo

We describe the experimental framework that we have developed to study the use of synthetic aperture in GNSS receivers to estimate and mitigate multipath interference. By combining the signal received by a single moving antenna during different time instan ...

Electromagnetic, complex image model of a large area RF resonant antenna as inductive plasma source

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier

A large area antenna generates a plasma by both inductive and capacitive coupling; it is an electromagnetically coupled plasma source. In this work, experiments on a large area planar RF antenna source are interpreted in terms of a multi-conductor transmis ...
