My concern is that am i right that my port 1 is touching the substance, Pec ground and the PEC patch? I have tried stimulated my drawing but it showed one warning which stated "Some higher propagating modes at port 1 are not considered in time domain calculation. This possibly leads to an inaccurate energy balance. Consider to reduce the port size or decrease the upper frequency limit." How do i get rid of this warning?
As what you have mentioned earlier "You have the option of floating the port location away from the boundary and fixing the port location at the edge of the pcb and adjusting its size too."? I have tried by picking the first point at the edge of grd pannel and the second point is at the top edge of the substance. Afterwards i select the discrete port and assign the port 1 as showed in the picture below:
Is this correct or you got any suggestion to improve it or recorrecting me?
