    Reg: PCB fabrication terminologies

    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?

    Reg: PCB fabrication terminologies

    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...

    How to design multiband microstrip antennas

    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...

    [moved] How to define integration line for this antenna?

    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)

    How to Excite an SMA port in HFSS?

    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.
