Abstract

This paper describes a method of measurement of miniaturized antenna gain in HF band based on a parallel plate cell. Compared to a free space outdoor approach this method offers two advantages: the use of a well defined environment and time efficiency. For the same external dimensions, it also has an advantage compared to TEM/GTEM cells designs in terms of useful antenna under test (AUT) space. This space is of a major importance in HF band since even miniature antennas can have considerable proportions. The proposed structure is composed of a parallel plate cell, whose construction is simple and not expensive. It offers a precision measurement with an error not exceeding 2.3 dB with respect to calibrated antenna gain and simulation results.
