Broadband Antenna Measurement Techniques -Phase II.

摘要

The report presents the results of a program to study advanced antenna measurement concepts and to breadboard certain promising instrumentation approaches. The applications of most interest are relatively high gain antennas in the 1-15GHz region. A typical instantaneous bandwidth of 1GHz is required. On the current phase of this program,an octave bandwidth 2-4GHz amplitude -only system was designed, breadboarded,and tested. This system will provide average pattern information over any portion of the 2-4GHz octave. This amplitude -only system is described,and measured data are presented. Tradeoff studies of a direct phase measurement system versus a group delay type of measurement system for broadband antenna measurements were completed.
