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...
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...
