Polarizarion Agile antenna

HEllo everybody, i m simulating a polarization agile antenna which can switch its polarization state from linear polarization: horizontal and vertical and circular polarization lhcp and rhcp depending on the diode on and off... thus i want immediate help over the same. i m using HFSS fro the simulation and i want to know how do i get the graph of axial ratio what all parameters should i use from the results option from hfss? kindly help me asap.. thanks to all in advance
