Antenna Measurements Using the Mirror Method with Gating in a Time Domain

This paper provides a principal overview of the time domain measurement instrumentation and information about the implementation of the time domain option in the Agilent PNA microwave network analyzer E8364A. The paper also presents practical experiences with antenna measurements realized by sweep mode of a vector network analyzer with data processing in a time domain. The new single antenna methods of gain and antenna radiation patterns measurements are presented. These mirror methods with gating in a time domain are based on the reflection coefficient measurements realized in the frequency domain with time domain data processing. These methods seem to be promising for measurements of gain and radiation patterns of ultra-wideband linearly polarized antennas. The paper compares the results of the new methods with the results of standard measurements.
