Pls, forum members i recently came across a paper online on how to optimize rectangular microstrip antenna using air gap technique. I have tried for more than two weeks without ant success, the design is in two phases. the first one is without air gap which i have uploaded the HFSS design here while i have no idea on how to design the second phase
Hello, i am designing using MCFIL component for microstrip sensor. but my S11 still 0.8 above approaching 1 . i am doing my final year project so i really really really need help here. Thanks in advance.
I'm not acquainted with CST, but in HFSS you cannot do that (as far as I know). You need to fit the equivalent circuits from the microstrip Antennas chapter in Balanis book (probably two RLC tanks regarding the two radiating edges) and then tune it using for example ads, until it fits the resonances obtained in CST or HFSS.

You wrote "microstrip" which implies a solid ground below. Do you want to design it on PCB or on chip ?
Try using an arc from the microstrip library, with angle = 360. Or, if 360 degrees isn't allowed, make two arcs that are each 180 degrees, and snap them together. I recently made a ring-quadrature hybrid coupler using four 90 degree arcs of varying widths, and a common radius. It worked quite well, and made a very nice circle.
Look at "Passive Circuit DG- microstrip Circuit" in the component palette at left hand side.. Pull out the designed structure, design it and optimize it by using Design Guide. Don't forget to simulate in Momentum..
