IMPACT OF ADDITIONAL ANTENNA ON ANTENNA COUPLING

Abstract

This paper deals with impact of additional antenna on mutual coupling of two VHF antennas. All the three antennas are tuned to the same constant frequency, placed on an idealized tail boom of a helicopter. The varied parameters are common distances of antennas and resistance of the additional antenna. It provides mainly the results of simulations, which were made on this subject, accompanied by real-life measures taken on an experimental model of tail boom.
