“…The distance averaging method was successfully used for measuring the antenna gain in a multipath site [2,3]. In previous papers we have presented several techniques for applying the distance averaging method in multipath sites in order to evaluate and to reduce [4] the impact of the common mode currents for field measurements on symmetrical and asymmetrical antennas.…”

This paper describes a method that can be applied for reducing the effect of the common mode currents when measuring the radiation of a small meandered monopole antenna. Moreover, it will be shown that the radiation of these currents can be extracted from the total radiated field. In order to validate our method, we considered a two-antenna measuring system consisting of a meandered monopole antenna (the antenna under test) and a loop antenna (the probe antenna). The measurements were performed in an anechoic chamber.

Common mode currents on antenna feeders usually occur when feeding a symmetric radiator through an asymmetric line, or when the ground plane is electrically small. Such currents may have magnitudes comparable to the feed currents and therefore have a major impact on the total radiated field. For antenna radiation measurements, both assessment and reduction of the common mode currents on antenna feeders are crucial. Techniques to discriminate antenna and feeder radiation are mainly needed for design and optimization purposes. Antenna gain measurements in a multipath site can be performed by using the distance averaging method. In this paper, we show that the distance averaging technique can be applied to reduce the effect of common mode currents for measuring the field radiated by symmetrical antennas. Two measuring configurations are proposed depending on the number of symmetry degrees of the antenna under test, and a differential approach for extracting the field created by the common mode currents was also developed. The experimental validation was performed by measuring a simple wire dipole and a log-periodic dipole array (LPDA) with a small square loop as a probe, both on the feeder side and on the feeder free side.
