excitation is giving by an unusual way below the notch.

There can be many problems possible. But I feel the way u connected your wave_port with the actually patch, is not looking good.
What you did is you drilled a hole (at specified position) in microstrip, then stuffed...
@MK28 Sorry, while explaining the experimental design we did, I lost touch with the main question.
So getting back on question, my teacher only looked for S(1,1) only while in your previous posts you have also mentioned about gain and s(2,1).
It will be good if you can provide with...
are you sure you want 10 MHz signal? Coz if you go for antenna with substrate then I dont think it will work. For small frequency like the one u want , u can use simple dipole. experts, correct me if I am wrong?
@MK28
I think i got confused with your last post.
Lets take a practical example, I simulated a rectangular patch for certain resonant frequency say 5.1 GHz. And I will optimize the design to get least possible S(1,1), in my problem statement, I got S(1,1) = -49 dB (as shown in graph below) and...
As per the basic microstrip/patch design, dielectric constant, resonant frequency and height of the substrate are given parameters and using this parameter we calculate W and L this length and width of microstrip/patch. It must be noted that formulas for microstrip and patch are little bit...
I am not new to this terminology but new to their design. Actually I am trying to implement one of the early modems for WiFi which uses 802.11ac and for that I require 256 QAM with 20 or 40 or 80 or even 160 MHz bandwidth. Can anyone provide me with the material to read or book title so that I...
I have never used ADS, but prefer AWR Microwave Office. In that we can connect a port with variable frequency. See if you have anything like this in ADS
Sat comm noise or atmospheric noise is thermal noise so 4kTB which is described in the last post. Similarly for shot noise we must take it as 4kTB only. Where as for flicker noise it should be kTB. This equation is known as Nyquist Equation of noise.
Our prof had given a challenge to design given amplifier and I stuck on how to go with power?
Q.) Design a transistor amplifier with f = 2.5 MHz, Pin = 1 mW and we must get Pout = 5 W. (No restriction on components we use, but we cannot Microwave Power Amplifier)
How should I proceed? I also...
