RF design with 2 layer stackup- possible?

Hey all,

I recently started designing RF PCB's and as a beginner, I stuck to the traditional 4 layers stack up for the RF boards (1-RF layer, 2-GND, 3-VCC, 4-Signal). But I am curious to know whether it is possible to design RF PCB's without compromising its performance with 2 layers. This would not only reduce the cost of my PCB production and also makes it easy to design.

You can do it with 1 layer and with 0 layer.

Details, details, details.
You have not told us what the circuit is supposed to do and the operating frequency, voltage, power.

oops, my bad. I am planning to make this RF board for a BLE application with ESP32-PICO-D4(50ohms impedance) as the MCU and Johanson's 2450at18a100e antenna(50ohms impedance). So, is it possible to design the transmission line between the MCU and antenna for 50ohms impedance on a 2 layer stack-up? If yes, how can I do that?

Operating frequency - 2.4GHz
Voltage - 3.3V

I hope this gave you some details.
