Abstract:

A new Ku‑band antenna system has been developed to support passive positioning and navigation (PPN) using Ku‑band signals of opportunity (SoOP) transmitted by low Earth orbit (LEO) satellites. The compact seven‑element antenna is low‑cost and easy to fabricate. Its radiation pattern is optimized to provide stable signal‑to‑noise ratio (SNR) across most of the sky above 25° elevation, enabling longer and more consistent PPN operation without requiring active beam‑steering to track rapidly moving LEO satellites. The pattern also suppresses low‑elevation reception to reduce interference from terrestrial sources. The design can be readily scaled for use with different LEO constellations and frequency bands. This report describes the design methodology, operating principles, fabrication process, and measurement validation of the antenna system.
