Gain and Directivity of an Array
Hello,
I am simulating a linear array of 25 dipoles with all the elements placed along the X-axis and oriented along the Z-axis. I did a Far Field Request such that theta varies from -90 deg to +90 deg and phi=0 deg. In POSTFEKO I can see that the directivity vs. theta plot is exactly same as the gain vs. theta plot. Why is this so?
