RF Input of a WIFI Energy Harvester in Schematic

Hello all!

I wanna ask some help regarding the input signal of our Wi-Fi energy harvester. We are targeting to use both the 2.4GHz and 5GHz frequency, one at a time. This signal will be the input of our rectifier. My question is how are we going to generate the harvested input from the Wi-Fi signal in our schematic simulation.

There's a comment that says, "generally, continuous sinusoidal or burst sinusoidal, e.g. ASK signal is used. OFDM waveform or waveform which has large peak factor is appropriate, since we assume WiFi signal." But how can we generate those using the schematic editor in cdesigner? I really am confuse in generating the input harvested from the Wi-Fi signal since we know that its amplitude is not constant from time to time. Can we use the port element?

Thank you all for your help.

It is easy.
Capture I(t) and Q(t) of Actual Wifi Signal by using Real Time Spectrum Analyizer.
Then use piece-wise linear sources for I/Q upmixer.

If you don't have Real Time Spectrum Analyizer, generate I(t) and Q(t)
by signal flow simulator such as Keysight-ADS-Ptolemy, Keysight-SystemVue, MathWorks-MATLAB, etc.

If you don't have them, generate I(t) and Q(t) by your own program such as C, C++, C#, etc.
If you can understand OFDM, it is not so difficult.

Right.

What do you want to mean ?
Use correct terminology.
