4.2 Mutual impedanceMatlab programThe program computes real and imaginary part of the mutual impedance of antennas depending on the length
of the dipole l,
on the shift between the centers of the dipoles h and
on the distance of the dipole axes d.
Parameters are entered to the program multiplied by the wave-number, i.e. as kl, kh and
kd.
First the path of Matlab has to be redirected to the folder Impedance.
The program is run calling the m-file vzimp.m.
Leaving the introductory window, which brings the basic information about the program and which
serves for the selection of a chart to be displayed (which variable is going to vary), values
of kl, kh and kd have to be entered.
The type of entered parameters depends on the setting in the introductory window (which chart is
going to be displayed and which variable is going to vary). For the varying variable, its minimum
value and its maximum one have to be given. Pushing the button Compute (if one of values is swept),
a new window is opened, where the course of the real part and the imaginary one of the mutual impedance
is depicted with respect to the selected varying parameter.
The button Exit
serves for finishing the program and the button
Back can be
used for a new run of the program.
