A Simple Methodology to Eliminate Noise in the Antennas Dipoles Measurements

摘要

The Measurements of dipole antenna outside the shielded room or semi anechoic chamber using an oscilloscope most often present problems due to the high input impedance of the dipole at low frequencies. The oscilloscope is susceptible to noise in low frequencies and 50 and 60 Hz is often the greatest signal received. Within this context, this paper presents a simple procedure with low costs to solve this problem.
