Thank you for the reply. Sir, so first the manufactures takes a PCB board with copper thickness of 17.5 microns , then they will add another copper layer on top of original 17.5 microns such that the finished copper trace is 35 microns. Is my interpretation correct sir?
hello there, can anyone please help me in understanding start cu(copper) thickness and finish cu(copper) thickness in the below invoice. I need to fabricate a PCB with copper thickness of 35 microns. If we consider the start cu(copper) thickness is 17.5mm and finish cu(copper) thickness is 35...
1) The circumference of the slot is lamda/2 at the operating band if it lies inside the structure. if you create an open slot then the length of the slot should be lamda/4.
2) are you exciting the antenna with inset or coaxial feed?
3) suppose if you want to design antenna operating at 1,2,3...
i think your using lumped port excitation, in that case, the interation line is taken from the top conductor to the bottom conductor ( in this case your feed line)
for lumped port exciation draw a circle at the end of the SMA connector covering the outer conductor.....then apply the lumped port excitation to that circle.
HI, sorry for the late reply, I am trying to simulate the antenna given in the following link...when i used the quarter wavelength radiation box ..i could not get the desired retun loss
.....i am also attaching you the HFSS file for reference...

Hi, I would like to design a 28 GHz patch antenna in HFSS.....i have a doubt regarding radiation box...should i keep the general lambd/4 size radiation box? or else?.....
