Design and Manufacturing of a Low-Profile Coaxial-to-Dual Ridge Waveguide Adapter for CubeSat Reflectarray Antenna Systems

This work presents the design and manufacturing of a low-profile coaxial-to-dual ridge waveguide adapter operating in the X band from 8.025 GHz to 8.4 GHz. The adapter will connect the feed of the antenna system to the RF front-end. The…

Design and Optimization of Active and Passive Quasi-Periodic Structures for Beam Steering

This paper presents the direct optimization of active and passive reconfigurable quasi-periodic structures for beam steering. Two configurations are considered, an active reconfigurable reflectarray working between 24.5-27.5 GHz for 5G application, and a passive mechanical steered low profile transmitarray working…

Direct Optimisation of a Five-State Reconfigurable Reflectarray for 5G Applications

This paper presents the preliminary design of a reconfigurable reflectarray using a direct optimisation approach, which has not been done before. The reflectarray employs a five-state configuration based on an aperture-coupled stacked patch element, offering phase quantisation within a 320…

Method of Moment simulation of full Arctic Weather Satellite structure

The Arctic Weather Satellite is a single payload prototype for a meteorological constellation of SmallSats called EPS-Sterna. Previous analysis showed that the Arctic Weather Satellite radiometer suffers from significant spillover in the 54 GHz band. To accurately model the scattering…

Uncertainty Quantification for the Reflector Antenna in the Copernicus Imaging Microwave Radiometer

The European Space Agency is currently working on realizing the Copernicus Imaging Microwave Radiometer (CIMR) which is a satellite-based multi-frequency microwave radiometer and one of the most ambitious missions of the Copernicus space segment. In this paper, results from the…

Full Wave Modelling and Design of a Baffle for the HERTZ 2.0 Compact Antenna Test Range

A baffle has the purpose of preventing the feed of a compact antenna test range to radiate in the quiet zone and it is typically constituted by a cylindrical structure covered by pyramidal absorbers. In this paper we describe the…

Determination of Manufacturing Tolerances using Uncertainty Quantification for the Realization of a Dual Circularly Polarized Elliptical Feed Horn

The manufacturing tolerances for the realization of a dual circularly polarized elliptical feed horn designed for a high gain deployable K-Band reflectarray antenna-system are determined. The tolerances are found using higher-order uncertainty quantification. Measurement results are presented for comparison with…

Determination of Manufacturing Tolerances of a Feed Horn using Uncertainty Quantification

This work presents the realization of a feed horn designed for a high-gain deployable K-Band reflectarray antenna-system placed on an 8U CubeSat platform that is to be used in an in-orbit technology demonstration. The main focus of this work is…

Detailed Electrical Design of a Novel High Performance Compensated Compact Antenna Test Range

The detailed electrical design of a new compensated compact antenna test range (CATR) to be installed in the HERTZ 2.0 measurement facility at the European Space Agency (ESA) is described. The CATR meets the stringent requirement of an overall peak-to-peak…

Computational Investigation of the DTU-ESA 12 GHz VAST12 Validation Standard Antenna to Identify Features Contributing to the Radiated Field

In this paper, we present a computational model of the DTU-ESA Standard Validation antenna VAST12, and investigate the impact of how different features on the antenna impact the radiation pattern. It is shown that the termination of the central tube,…

Design of a dual circularly polarized elliptical feed horn for CubeSat reflectarray applications

A low loss dual circularly polarized feed antenna for a high gain deployable K-band reflectarray antenna on a CubeSat platform is designed. The feed consists of an elliptical horn antenna and its feed network, which will be optimized alongside with…

Antennas on CubeSat platforms: Accurate RF predictions

A typical 3U and 6U CubeSat hosting antennas ranging from the low UHF to the higher Ka band are modelled in the ESTEAM software package. The antennas are inspired by recent designs published in the literature. RF performances of the…
