In practice, the most commonly quoted parameter in regards to antennas is S11. S11 represents how much power is reflected from the antenna, and hence is known as thereflection coefficient(sometimes written as gamma: orreturn loss. If S11=0 dB, then all the power is reflected from the antenn...
These antenna frequency bands may be single, dual, or multiband. The small microstrip antenna, without connecting any external devices like switches, resonators, and passive elements, does not show any variations in their simulation and measurement results like return loss...
s11 parameter Hi, I have a question regarding S11 parameter. Usually it is sad that antenna should not have S11 above -6dB (or even -10dB). I have an...

s11 parameter hfss i am sorry , i am not clear about what your said , i don't think define all the slot to be ports. maybe the slots are the special structure that you want to simulate,so if you want the s11 ,just see the result of input port s11 ...
We will see S parameters(scattering parameters) which include S11/S22(Reflection coefficient),S12(Isolation) and S21(Insertion loss). S parametersare popular in RF/Microwave circuit design and testing. Following are Scattering parameters used for measuring/characterizing the RF device. ...
