Impact reduction of common mode currents for field measurements on a meandered monopole antenna

Abstract

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.
