Laplace Beamshapes for Phased-Array Imaging

Paul Hurley, Matthieu Martin Jean-André Simeoni

The imaging capabilities of phased-array systems are governed by the properties of their array beamshape, directly linked to the instrument impulse response. To ensure good spatial resolution, beamshapes are designed with a very narrow main lobe, at the co ...

Imaging in radio interferometry by iterative subset scanning using a modified amp algorithm

Paul Hurley, Matthieu Martin Jean-André Simeoni, Giovanni Cherubini, Sanaz Kazemi

Imaging techniques in radio interferometry often face a significant challenge posed by the large number of antenna signals received, from which the image information needs to be extracted. Beam- forming is envisaged to reduce the rate required for transpor ...

Compact Corrugated Feedhorns With High Gaussian Coupling Efficiency and-60 dB Sidelobes

We demonstrate that very high performance, extremely compact, scalar corrugated feedhorns can be designed and constructed by optimizing the excitation and phasing of the HE11, HE12, and HE13 modes near the throat of the horn while limiting excitation of hi ...

Tunable radiator for small satellite application

Jean-Daniel Landis, Frédéric Bongard, Tomislav Debogovic, Pedro Robustillo Bayon, Nevena Saponjic, Mikaël Krummen

A tunable radiator for space application has been developed to meet stringent requirements in terms of electrical and environmental specifications but also low mass, simple manufacturing and low cost. The element is based on the folded PIFA antenna, with s ...

Analysis and Design of Mobile Device Antenna-Speaker Integration for Optimum Over-the-Air Performance

Juan Ramon Mosig, Nicolas Chavannes

In this paper, the mutual coupling between a mobile device antenna and a closely integrated miniature moving-coil speaker is investigated. The analysis focuses on the speaker radio-frequency harmonic resonance characteristics and the antenna radiation effi ...

Electron Cyclotron Emission (ECE) And Correlation ECE Diagnostic On TCV

Laurie Porte, Philippe Marmillod, Matteo Fontana

The electron cyclotron emission (ECE) and correlation ECE diagnostics in TCV have been upgraded during its 2014 shutdown; this paper will provide a brief overview on their updated architecture and capabilities. The ECE system is equipped with two radiomete ...

Dual-polarized one-dimensional leaky wave antenna

Juan Ramon Mosig, Marc Esquius Morote, Maria Garcia Vigueras

In this abstract we present a one-dimensional leakywave antenna fed from two ports that provides a dual-polarized radiation pattern. It is the first time that dual-polarized radiation is achieved from a single one-dimensional leaky-wave radiating aperture. ...

Wideband, low profile and circularly polarized K/Ka band antenna

Juan Ramon Mosig, Joana Rita Alves dos Santos Silva, Przemyslaw Andrzej Gorski

This paper presents a wideband circularly polarized planar antenna element for both K and Ka bands. The proposed solution is composed by several thin layers of dielectric substrate that allocate two circular stacked patches, a crossed-slot and two fork-sha ...
