Abstract :
This paper discusses the details surrounding the measurement of electrically small antennas, common errors in measurements, and the implications of these errors on system performance. Issues of small ground planes, cable effects, and efficiency measurements are examined for their apparent and interrelated effects on input impedance, radiation patterns, and system performance.
