positive return loss
I have modeled a partch antenna (including the feed structure). But the problem is when I plot the Return Loss (dB) over the frequency range there is a section where the return loss is > 0 db and reaches a peak of 6dB.
Thats doesn't make sence to me. It's a passive...
How can I calculate/plot the Gain and Efficiency of my antenna?
(1) At single/solution frequency
(2) Over the frequency sweep
Apologize about the reposting but I am clueless on this?
I feed to feed a Patch Antenna (Edge Fed with MStrip Line) where the Input impedance at the edge of my antenna varies from rapidly over my band of interest. Note: I have resonance at the centre freq but below and above that its comples Impedance.
Any suggestion on what kind of...
I am new to EM (So to HFSS). I have used FDTD for my initial Patch Antenna simulation so I have some basic concepts. Now I need to do a fast start in HFSS.
I will summarize my situation so that it helps your suggestions.
I know how to calculate dimensions for the patch and substrate for...
