aaj toh party banti hai idgaf breaking the 9 barrier for me was soooo imp- peace of mind at home wise
and these endsems were genuinely one of the most stressful times since jee. pressure from home, friends, some people i really respect oh my god
every word i wrote was calculated to a T.
IDK WHY I'M SO HAPPY I JUST AM THIS IS INSANE TO ME

The antenna is: bow tie antenna, the shape sort of gives it away.
Now coming to the circuit:
This circuit is called a comb generator, this particular model probably generates 100MHz spaced signal cuz that's the oscillator used.
These are widely used in EMI/EMC testing if I'm not wrong.
A clock's trapezoidal edges create harmonics via the sinc-function envelope now A comb generator is designed to maximize this: it drives a nonlinear element (step-recovery diode mostly) as hard as possible with a fast transition edge drive signal, generating a dense, flat "comb" of harmonics spanning octaves.
100 MHz crystal oscillator (the "100.00R EC3951" XO) generates the fundamental which drives a balun for balanced coupling and into what I'm guessing is an SRD (the banded SOD323 package sitting right at the balun op but, it could just be a Schottky, hard to confirm). The SK17 Schottky downstream looks like it's serving a separate function not sure...
Op should look like this in the SA

RF quiz: what does this circuit do? Will post the answer in the morning.

Now why bowtie antenna you ask?
Go back to dipole/ halfwave dipole you often design them for one frequency, it is fixed by length but for bowtie they go with the angle.
What's actually happening: the flared shape means current has tons of different path lengths available on the same structure. At the feedpoint, the shorter paths handle higher frequencies. Out toward the wider edges, longer paths handle lower frequencies.
I think of it as basically several different "dipole lengths" stacked into one continuous shape.
That's why a bowtie gets ~33% bandwidth vs ~8% for a thin dipole it's not one antenna tuned to one freq, it's a bunch of slightly different ones overlapping. (Wideband)

2.92 and SMA!
What's the difference?
TL;DR : one is designed for high frequency the other is not.
