A deployable parallel-plate slot array antenna is being developed for the Synthetic Aperture Radar (SAR) sensor onboard small satellite. This parallel-plate slot array antenna is designed to operate in X-band frequency with vertically polarized radiation. The antenna is designed entirely by using HFSS simulator. From the results of simulation, it is shown that at the center frequency (9.65 GHz), one...
A new design concept of a compact satellite antenna module for automotive application is presented, enabling mobile reception of all common navigation systems, e.g. GPS in L1&L2 bands, Galileo, GLONASS, BeiDou, as well as reception of satellite digital audio radio service (SDARS). A new design concept allows easy fabrication in combination with high reception properties. The performance of the...
The paper provides an overview of the most significant space antenna products and technologies for Observation, Exploration and Navigation (OEN) developed by ThalesAleniaSpace-Italia (TAS-I) over more than 30 years. These antennas provided a determinant contribution to the scientific community in understanding earth environment and solar planets. An outline of today key developments is also presented.
This paper presents a compact X-band antenna with an isoflux radiation pattern and circular polarization. It consists of a miniaturized helix antenna connected to a stripline circuit that provides a sequential rotation feeding. The antenna is arranged over a vertically corrugated ground plane and it has been optimized for a CubeSat 3U nano-satellite platform. Its design, manufacture and results are...
Lockheed Martin Space Systems Company has pioneered advanced antenna solutions over several decades and built a wider range of payload solutions than any other company in the industry. This paper presents a few antenna technologies which has been successfully developed and flown over the years.
In the current work we focus on sparse array design employing overlapping radiating elements. In this case, the underlying sparse grid shapes the broadside directivity far-field pattern while the overlapping flat-top producing sub-arrays eliminate the scanning loses. In detail, when overlapping arrays are involved the design process is as follows: Perform broadside design, (not scanning beam), using...
A 1.1-m reflectarray antenna has been designed, manufactured and tested to fulfil the requirements of a satellite antenna in Ku-band that provides South American coverage in Tx and Rx. The reflectarray cells consist of four dipoles for each polarization in two dielectric layers, which were selected because of their simplicity and high performance. The dipole dimensions are optimized in all the reflectarray...
This paper describes a Ku band, electronic beam steered array, operating at 10.7 GHz to 12.7 GHz intended for satellite DVB reception. The beam steering operates in the azimuth plane and the antenna also has a fixed beam squint at 23° elevation selected as appropriate for UK operation. This allows the distinct advantage of the antenna having the ability to be mounted vertically on a wall, by virtue...
