How to set up wireless communication with Arduino (ATMega168)?

I am doing a small project and I need the microcontroller to be on a rotating platform and to have a connection with it. The required data transfer rate is 27,000 bps (although I will be happy with 9600), the distance is 3-5 cm. The main problem is that the transmitting / receiving part on the MK needs to eat as little as possible because it is powered by an air transformer. Ideally, it would be within 50 mA. What can you advise?

Who can say anything about infrared communication?

You probably already know, but I’ll voice it anyway - there are UART-Bluetooth modules, they cost about $ 10. I don't know how much they eat. They are called Bluetooth UART HC-05, Bluetooth UART HC-06.

Bluetooth and XBee have already been offered. It remains to add modules based on nRF24L01+ for comparison. They are cheap (about $2-$5), popular and quite economical (about 12mA for transmitting and 11mA for receiving, there is also a sleep mode with meager consumption).
