Broadband frame antenna having a constant antenna factor for measuring magnetic field strength

摘要

The object frequently exists of measuring the magnetic field strength in as broadband a manner as possible on the one hand as a useful field strength and on the other hand as an interference field strength. The measurement arrangement described here uses a frame antenna operated in the short-circuit mode, with a built-in current transformer. This results in a constant antenna factor over a wide frequency range, which antenna factor can be calculated from the dimensions.
