Abstract

Antenna assemblies and associated satellite tracking systems that may include a low profile two-way antenna arrangement, tracking systems, and applications thereof. Applications for the system include military, civilian, and domestic emergency response applications. The antenna arrangements may be configured to form a spatial element array able to track a satellite in an elevation plane by electronically dynamically targeting the antenna arrangement and/or mechanically dynamically rotating the antenna arrangements about transverse axes giving rise to generation of respective elevation angles and dynamically changing the respective distances between the axes whilst maintaining a predefined relationship between said distances and the respective elevation angles. The system provides dynamic tracking of satellite signals and can be used for satellite communications on moving vehicles in military and civilian applications.

Claims

1. An apparatus comprising a low profile two-way Ka and/or Ku band antenna assembly for use on moving military and/or civilian vehicles.

2. A method comprising tracking of satellites using a low profile Ka and/or Ku band antenna for use on moving military and/or civilian vehicles.
