hello i am not well in HFSS can any one please tel me how todo the connexin (i use a rectangle for patch and for GND (PerfectE) how connect them) in figure attached and if i must use a coaxial or simple port
thanks in advance
the set up is quite easy you can do it two ways either have your coaxial connector connected the way shown or through a via going passing substrate. to do this draw the inner conductor touching the inverted-F and the outer coax touching the ground plane.if you would like i can show you how to do it at the condition that you have planar inverted F designed already on hfss.
