Antenna complex input impedance into real impedance
I'm trying to design a loop antenna and make it resonate around 100 MHz.
Using a standard 50 ohms port, the resonating frequency is not at 100 MHz. Since I cannot change the geometry, I'm going to ...

Zener behaving strangely
I have recently put together a trivial low-voltage interlock circuit to prevent over-discharge of a 9v battery pack.
I use a Potential divider of 1600 / 5600 ohm to produce 4.7v when Vcc is 7.2.
I ...

S21 calculation
In this post
It mentioned that there's a factor 2 in S21 value.
But I'm still don't understand why there's a 2 in it.
My schematic is shown below.
Shouldn't S21 = Vout/Vgen?
My question is: where is ...
