INTERMODULATION CHARACTERISTICS OF COMPLEX RANDOM ANTENNAS
ABSTRACT
The results of experimental investigations of a complex random antenna (RA) comprised of elements emitting a harmonic and a noise signal, are given. Spectral oscillograms of signals emitted by the RA in various operations modes are presented. It is demonstrated that a signal of a complex RA is generated by the basic and spurious emissions of its elements, intermodulation (IM) conversion products and electromagnetic background in the room, where the RA is located.
Investigation methods and quantitative criteria for evaluation of the second-order IM conversion products in a complex RA are proposed. The materials given in this article represent the reference data for studying RAs by means of a computer statistical simulation method.
RA investigation and simulation modeling are required for solution of problems related to ensuring of electromagnetic compatibility and safety of radioelectronic devices as well as for confidential information protection.
