3D-printed Ka-band Antenna Based on Stereolithography

Juan Ramon Mosig, Tomislav Debogovic, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

This paper presents a circularly-polarized dual-band antenna for Ka-band satellite communications which operates simultaneously in both civil and military downlink (17.7-21.2 GHz) and uplink (27.5-31 GHz) bands. The antenna is composed of a metallic ridged ...

Estimation Bounds for GNSS Synthetic Aperture Techniques

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

This paper characterizes the estimation performance of synthetic aperture (SA) techniques in the context of moving GNSS receivers. Under the assumption of a stationary channel, SA techniques transform a single antenna into a virtual array. We first introdu ...

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 ...

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

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

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 ...

In-Plane Plasmonic Antenna Arrays with Surface Nanogaps for Giant Fluorescence Enhancement

Jürgen Brugger, Duncan Thomas Lindsay Alexander, Pamina Winkler, Valentin Flauraud, Raju Regmi

Optical nanoantennas have a great potential for enhancing light-matter interactions at the nanometer scale, yet fabrication accuracy and lack of scalability currently limit ultimate antenna performance and applications. In most designs, the region of maxim ...

Multi-criteria analysis for the integrated performance assessment of complex fenestration systems

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Chantal Basurto Dávila

Complex fenestration systems (CFS) designed to collect and redirect daylight from the sky-vault are generally placed on the upper part of a window in order to improve the distribution of indoor daylight. Due to their additional function as solar protection ...
