* In the '''Port Definition''' Dialog, set the number of ports equal to one. Associate all the four lumped sources with Port 1. Set the value of the '''Port Impedance''' properly equal to the characteristic impedance of the coaxial feed line.
NOTE: {{Note|EM.Cube will set the internal impedance of each of the four coupled lumped sources equal to four times the specified port (or line) impedance since the coaxial port is a parallel connection of the four individual lumped sources.}}
