Broadbeam microstrip patch antenna using higher order modes

The aim of this contribution is to assess the potential of using various microstrip radiating elements excited with different modes to achieve wide pattern beamwidths. The proposed antenna is made in classic microstrip technology and consists of a circular ...

Four-Port Broadband Orthomode Transducer Enabling Arbitrary Interelement Spacing

Juan Ramon Mosig, Anja Skrivervik, Emile Jacques de Rijk, Tomislav Debogovic, Maria Garcia Vigueras, Santiago Capdevila Cascante, Esteban Menargues Gomez

This paper reports a novel methodology to design broadband orthomode transducers with two arbitrarily spaced ports carrying orthogonal linear polarizations. The component is based on a combination of two Boifot junctions through a series of power dividers ...

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 ...

Reconfigurable Pixel-Layer Isolator for Frequency-Tunable On-Frequency Repeaters

Daniel Rodrigo Lopez

The maximum gain in on-frequency repeaters is limited by the isolation level between their two antennas due to close-loop stability conditions. In this letter, a novel pixel-layer isolator for tunable on-frequency repeaters is presented. The scattered fiel ...

TOLPA (Tripod Omnidirectional Low Profile Antenna): a vertically polarized antenna with 90% bandwidth

Jean-François Zürcher

A new vertically polarized omnidirectional antenna, inspired by an old design, has been studied, optimized, realized and measured. With a radiation pattern similar to the classical monopole on a ground plane, the proposed antenna concept provides a much la ...

Shaped Beam Synthesis of Arrays via Sequential Convex Optimizations

Juan Ramon Mosig, Anja Skrivervik, Benjamin Fuchs

A method to synthesize shaped beams with antenna arrays is presented. Specifically, the element excitations are determined such that the array radiates a power pattern that approximates a desired shape. To efficiently solve this problem, an iterative algor ...

A New Sensor Platform for Investigating Turbulence in Stratified Coastal Environments

Ulrich Lemmin, Damien Bouffard

Characterizing and quantifying vertical exchange processes is essential for understanding physical and biological dynamics in stratified lakes and oceans. Unfortunately, the role of mixing is still poorly understood because of the challenges of conducting ...

A New Power Divider Architecture for Suspended Strip Line

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

In this paper the authors present a novel power divider architecture intended to be used with the Suspended Strip Line (SSL) transmission line. The new antenna array systems, that are designed to work in the millimetre wave ranges, are suffering from the l ...

Low voltage vertical flaps arrays as optical modulating elements for reflective display and switchable gratings

Nico de Rooij, Wilfried Noell, Fabio Jutzi

A novel technology is presented for arrays of vertical flaps as optically modulating elements which are actuated electrostatically to horizontal position at low voltages of 30-50V. One application is a reflective display exhibiting a contrast ratio of 1:95 ...
