I am currently designing a probe-fed stack patch for frequency band 27.5~30GHz, the structure is down below.
The gap I cut around the feeding probe on the driven patch seems to increase the BW, but will make S21 pretty awful(before cut ~-18dB)
Is there a way I can do on the current structure to make S21 lower?
The following pictures are the surface J
