Dielectric Covered Microstrip Patch Antennas

摘要

Microstrip antennas have many properties that make them suitable for airborne and satellite communications systems. These antennas are low in cost and lightweight. For these reasons, Rome Air Development Center (RADC) is interested in verifying and augmenting existing design models for these antennas. This report will present the theory and results for modeling microstrip antennas that are covered with a sheet of dielectric material. There are several reasons for designing a microstrip antenna covered with a dielectric material. This configuration would allow the modeling of antennas with an integrated radome. A cover layer could possibly be used to support a polarizer; to mount additional antenna elements on top of the cover layer to provide bandwidth enhancements; or to be used as a dual frequency antenna.
