In this paper we address methods for characterizing small, low-gain antennas that are intended to be operated autonomously by a passive transponder chip. We present a way to perform accurate 3D gain measurements by means of a small, battery-powered, calibrated signal source and a two axis rotation apparatus. From the measurement results the directional pattern and the antenna efficiency are derived. We perform a test measurement of a half-wavelength dipole and find good
accordance of measured and theoretical data.
