Analysis of electromagnetic interference between antennas

In an electromagnetic interference (EMI) phenomenon, there is at least a transmitter antenna, and a receiver antenna which is also called as a victim system. To be able to understand this phenomenon analytically, power radiation from the transmitter and power received by the victim antenna should be evaluated. Electric fields of the antennas are used for power intensity calculations. Pattern function with respect to the spherical coordinates is a very important factor in the evaluation of an antenna?s electric field. In this thesis, two fundamental cases for EMI analysis are studied. First, a dipole antenna is considered as a transmitter and a microstrip patch antenna is considered as a victim receiver. Secondly, a circular loop antenna and a microstrip patch antenna are taken into consideration as a transmitter and a receiver, respectively. For both cases, their interference mechanisms are shown analytically. The results of the calculations are shown graphically in the MATLAB simulations.
