Hi everyone,

I am trying to interpret the results accumulated from my monopole measurement in an Anechoic Chamber. I constructed a reconfigurable monopole and the simulations show accurate results. However, when it comes to measuring the fabricated prototype, I am confused as to what results to compare my simulations to. I simulated the antenna in CST and the polar plot for the monopole shows obvious switching of the radiation pattern. In the anechoic chamber, the transmitting antenna which is a horn antenna, is set to a X-pol and Co-pol (horizontal and vertical) during measurement. When I obtain the results after measurement, I receive a lot of data of both X-pol and Co-pol. Which data corresponds to my simulation in CST? Thanks.
