Investigation of Antennas for a High-Sensitivity Polarization Measurement Sensor

reportActive / Technical Report | Accession Number: ADA530246 | Open PDF

Abstract:

The polarization properties of the electromagnetic fields radiated by a scanning array antenna enclosed within an aerodynamic dielectric radome are analyzed and measured. It is known that the radome causes depolarization effects, and it is of interest to measure the depolarization to a high level of sensitivity. A polarization measurement procedure is developed using a pure linearly polarized reference antenna. A design for this antenna is proposed that is expected to have less than -50 dB cross-polarization in the main beam. The same antenna may be employed as a precision polarization sensor of an arbitrary incoming EM wave.
