Also, I'm going to further tune the antenna with matching network to better match my source.

I ilke that they can be manufactured on FR4 which means high reproducibility and hence low error margin. Both do promise about +10dBi gain, with the biquad a little bit narrower and hence with better directivity. I have noticed your biquad and batwing antenna designs. To break 2 km range, I'm thinking about a couple of offset dishes 1m diameter (expect to reach +25dBi), and looking for a suitable feed horn.

I'm working with Bluetooth 5 enabled microcontrollers, and for an experiment want to build a long range symmetrical setup using vanilla nRF52840 MCU (+8dBm max). First of all, please let me thank you for sharing the designs! This is absolutely stunning what you guys are doing here.
