Compact embedded antenna

摘要

An antenna embedded into armor plates. The armor material is of low dielectric constant preferably less than 20 permitting radio radiation to be emitted through the armor by the antenna. In a preferred embodiment the armor is a composite of different materials, with the antenna placed between elements of the armor, creating a multi-level design. The antenna elements are preferably printed for low-profile and ease of integration or the antenna elements can be fabricated from larger elements and placed into a space between vehicle and armor or in a cavity cut into the vehicle or armor.

主权项

1. An armor embedded radio antenna system for providing radio communication for an armored vehicle comprising:
A) an armored vehicle, B) at least one embedded radio antenna system mounted on the armored vehicle, the antenna system comprising;
1) at least one layer of low dielectric armor material,2) a flat panel radiator located behind said at least one layer of low dielectric armor material, the flat panel radiator comprising:
i) a central radiator comprised of four elongated slots defining an approximately square slot radiator,ii) a loaded slot radiator surrounded by the central radiator,iii) a parasitic loop radiator surrounding the central radiator;3) an insulator layer located behind said flat panel radiator, and4) a feed line located behind said insulator layer.
