Hi,
I have a problem in my design, actually I am designing UWB rectangular monopole antenna.
I dont know how to plot radiation patterns in E-palne and H-plane for different frequencies.
what parameter does affect so much S11 and VSWR in antenna design. i am using HFSS ver13.
Please I need hep.

for radiation pattern, go to Hfss/Results / Create report / Farfield / Radiation pattern
for S11, input impedance will affect the s11 parameter. most of the times, your input impedance should be 50 ohms, and your matching by choosing proper width and height of microstrip feed line could be well...
