Global Synthesis Method for the Optimization of Multifeed EBG Antennas

Figure 9

Radiation pattern comparison in the E-plane. 3 radiation patterns are plotted. The first plot is obtained by the linear combination of the active element patterns; the second is CST MWS posttreatment taking into account the feed network scattering matrix; and the third plot results from an entire structure simulation (the feed network and the EBG antenna are meshed under the same CST simulation).
