A simple electronic warfare device

[not_defined2]

In Ukraine, the activity of any amateur radio transmitters during the war is prohibited. Any electronic warfare system can jam the signals of the Ukrainian air defense system and distract radars, so it can only be used by the military. I understand this, but in the future I intend to use electronic warfare systems illegally. For example, to protect a private house. I often write something on the Internet that the Russians may not like, and if long-range drones were cheaper, they could direct them at the house.
Now I don’t need an electronic warfare device. I live in the Kyiv region and Russian FPV drones don’t fly here. But I need an electronic warfare device for the future.

I made a simple electronic warfare device. IRF3205 transistor, NE555 pulse generator module, converted high-voltage transformer of an old CRT TV (15 turns of the primary winding are wound with litz wire), spark gap, oscillatory circuit and two wires. The spark gap is connected in parallel to the oscillatory circuit capacitor, two wires extend from the ends of the capacitor in different directions. This device allows me to create radio interference to mobile communications without an oscillatory circuit. When I turn it on, an icon of a crossed-out circle appears on the mobile. It works at a distance of 1-2 meters completely, and at a distance of up to 20 meters the connection drops.

I need your advice on how to modify this oscillatory circuit pumping device to operate at a WiFi frequency of 2.5 GHz and make the antenna more directional (make the oscillatory circuit built into the antenna) and increase the efficiency to create radio interference at a distance of at least a couple of kilometers.

What you are asking is quite a difficult undertaking. Building any kind of circuit to operate at 2.5 GHz is challenging. Building one that operates at significant power levels is even more difficult. What works at low frequencies may or may not be practical at UHF and above. At these frequencies power and elevation above the ground are what you need. It is my hope that you will find the solution that you need.

At the output of the high-voltage transformer, I need an improved circuit. If I install a rectifier, problems arise. If there is no capacitor after the rectifier, a continuous arc lights up, which simply closes the secondary winding of the transformer to the inductance coil. If there is a resistor and a capacitor after the rectifier, the pulse frequency is low and the ultra-high frequency oscillatory circuit does not have time to pump up.

Sorry, but what you're talking about is highly illegal, and would cause widespread interference over all kinds of services -including Police, Ambulances etc. It's NOT a 2.5GHz 'blocker' it's a really crappy wideband interference source.
