Well if we follow the historic development arc, frequency-scanning waveguide arrays would come next. Nicely, very minimal modification required, and you can start cranking up the antenna gain. Mostly just a physical fabrication challenge, which is hobby-approachable. https://www.radartutorial.eu/06.antennas/Phased%20Array%20Antenna.en.html#fca https://www.radartutorial.eu/06.antennas/Phased%20Array%20An...
