Results on the High Altitude Environmental Tests of the Flat Antenna

Abstract

Aircraft is one of the major traffic facility for the mobile reception of the direct broadcasting satellite (DBS). In the development of the airborne DBS receiver, we must find the effect of the high altitude environment upon the characteristics of the flat antenna that is composed of dielectric substrate. We put the sub-array to the high altitude environmental (altitude, temperature, humidity) test, and got the result that the polyethylene form substrate can be used for the airborne antenna.
