First i want to specify I wrote wrong the part of "They are below -10 dB" it must be "They are above -10dB".
i tried many of ways to solve this problem but i couldn't. I changed the position of the feed, height of the pin, changing radius of the pin, teflon and outer cover(copper), changing materials of the pin, dielectric(teflon) and outer copper of the feed, also I add cavity back but nothing has happened so far. It's not working. As I see i'm doing everything properly but I don't know why it's not working. Can somebody help me ??
Also I can send the .cst file of the design if someone may check. I would be so appreciate...
Thanks again...
