Circularly polarized planar antenna with axially symmetric beamwidth reconfigurability

Anja Skrivervik, Hannes Bartle

This contribution presents the design of a compact circularly polarized antenna featuring beamwidth reconfiguration in both the horizontal and vertical planes. The observed radiation patterns in each of the reconfigurable states present axial symmetry and ...

Evaluation of a New Process for the Additive Manufacturing of Metal Antennas

This paper presents a new process for additively manufacturing purely metallic antennas based on Fused Deposition Modeling (FDM), with a proprietary filament developed using a hot extrusion method and composed by a mix of rounded shape copper powders with ...

Antenna for a Cranial Implant: Simulation Issues and Design Strategies

Anja Skrivervik, Zvonimir Sipus, Miroslav Veljovic

The design of a specific antenna for a cranial implant is used to illustrate design and simulation issues linked to implantable antennas. After a brief introduction, we will review the requirements for the antenna, and go through the design process, discus ...

IEEE2020

Many metamaterials, including metal wire grid, was invented to enhance the performance of the antenna in the last decade. A novel zero index metamaterial (ZIM), consisting of double metal layers with periodic circular perforation cells, was proposed and st ...

IEEE2020

Recent developments have enabled the practical realization of optical elements in which the polarization of light may vary spatially. We present an extension of Fourier optics-matrix Fourier optics-for understanding these devices and apply it to the design ...

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 ...

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 ...

Twisting Fluorescence through Extrinsic Chiral Antennas

Olivier Martin, Chen Yan, Xiaolong Wang

Plasmonic antennas and planar structures have been undergoing intensive developments in order to control the scattering and absorption of light. One specific class, extrinsic chiral surfaces, that does not possess 2-fold rotational symmetry exhibits strong ...

Linearly polarized GHz magnetization dynamics of spin helix modes in the ferrimagnetic insulator Cu_2OSeO_3

Dirk Grundler, Helmuth Berger

Linear dichroism — the polarization dependent absorption of electromagnetic waves— is routinely exploited in applications as diverse as structure determination of DNA or polarization filters in optical technologies. Here filamentary absorbers with a large ...
