Millimeter wave reflectarrays

چکیده
This paper is an overview of the mm-Wave reflectarrays developed at the LEAT (University of Nice Sophia AntipolisFrance) since October 2004. It addresses several topics: method of conception and design constraints of mmWave reflectarrays, influence and limitations of the reduction of the cell size, design and realization of ultra-low lobe reflectarrays by using prolate horns, design of simultaneous multi-lobe antenna. The field of application was initially the collision avoidance radar for to rescue helicopters with a design frequency of 94 GHz. The design concepts have been validated by experimental data.

Phase Characteristics of Subwavelength Antenna Elements for Efficient Design of Terahertz Frequency and Millimeter Wave Metasurfaces
In this paper the effects of subwavelength antenna resonator element dimensions on the anomalous reflection properties of metasurfaces operating in the millimeter wave and terahertz frequency regions are investigated. Such twodimensional structures are finding uses as flat optics in a variety of applications including beam steerers, reflectarrays, and broadband, polarization-independent radar a...

Engineered metamaterials offer unique functionalities for manipulating the spectral and spatial properties of electromagnetic waves in unconventional ways. Here, we report a novel approach for making reconfigurable metasurfaces capable of deflecting electromagnetic waves in an electronically controllable fashion. This is accomplished by tilting the phase front of waves through a two-dimensional...
متن کاملGallium Phosphide IMPATT Sources for Millimeter-Wave Applications
The potentiality of millimter-wave (mm-wave) double-drift region (DDR) impact avalanche transit time (IMPATT) diodes based on a wide bandgap (WBG) semiconductor material, Gallium Phosphide (GaP) has been explored in this paper. A non-sinusoidal voltage excited (NSVE) large-signal simulation method has been used to study the DC and high frequency characteristics of DDR GaP IMPATTs dsigned to ope...
متن کاملReflectivity of Reflectarrays Based on Dielectric Substrates
Problem statement: Reflectarrays provide a low cost and low profile solution for antennas required for high gain applications but their use is restricted in some applications due to the narrow bandwidth and high loss performance. These performance limitations can be attributed to different sources of reflectivity of the reflectarrays. This work provides a thorough investigation on the reflectiv...
