Based on your description, I gather that you are having problem fabricating and feeding the 60 GHz antenna accurately due to the tight tolerance and the small size of the feeding network and antenna structure.
You could look at the problem from a couple of perspective. I would have talked to...
differential +antenna
I believed you need to be clearer. What is your refernce impedance?
I dont think you design your antenna for 86.5 +j43 ohm rite?
Usually it is either 50 or 100 ohm for most system.
In that case you calibrate accordingly.

Sorry I mean either...
I believed I am using a similar circuit. I found out the isolation is mainly due to the bond wire coupling.
Is there a good way of modelling the signal coupling? If so, how?
Or if some one out there have a better design? I would like to know about it.
RF Switch
I also have a question, for the series -shunt switch design shown above, does any one know why capacitors are added between the gate and source and also between the gate and drain?
What is it purpose?
Dear all,
I am interested in designing a hi- isolation switch. I am having problem meeting my design specification of 60 to 70 dB isolation at 1 GHz.
1)Does anyone have any paper or material that can highlighted the possible issues with this type of high isolation switch design?
2) Or...
planar antenna construction
Hi
I think you need to be a bit more specific on what type of antenna you are talking about.
What sort of antennas are we talking about?? planar microstrip. planar monopole, etc???? Or more complex structure with multiple resonator such as a multi-band pifa?
Hi guys,
I am interested in finding out your view on integrated antenna?
For examples, is there any commercial value in doing integrated antenna design?
What are the pro and con etc.....
Best regards
folded monopole for am broadcast
Hi
I did a folded monopole a long time ago and I will try to see if I can answer your questions.
Feel free to correct me if I am wrong. Ans to your question are as follow
2) As its name suggest, it is a folded version of the folded dipole antenna.
1)...
Hi,
I am interested in designing a common gate amplifier but don't know where to start?
Also, will the common gate amplifier have similar gain as the common gate amplifier?
Is there anyone who can help me?
Many Thanks and Best regards
