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...
Sorry for being misleading, this Wilkinson power divider is part of my graduate school training program to let me get use to the software. I just want to know if today I have S parameter and the length of the feeding line, can I find the input impedance at the end of the feeding line with ADS...
Yes, but however between the 50 ohm and 70.7 ohm line still have some mismatch, I want to add another lambda/4 line to make it matches better. The point here is to use s parameter from HFSS and the length of 50 ohm line in ads to find the value of input impedance, but I have no clue how to do it.
I'm trying to design a Wilkinson power divider with HFSS, but I need to add a lambda/4 line between sqrt(2)Zo part and the Zo part as the pic shows for impedance matching , so I want to know the input impedance there. Can I do this with ADS by importing S parameter matrix to a SnP component in...
