Ka-Band AESA for Satellite Communications — Development and Challenges for Low SWaP-C

The demand for satellite communications that do not require terrestrial infrastructure is rapidly increasing, and the shift to Ka-band has become a hot topic. In general, AESA technology for SWaP becomes more challenging at Ka-band, but on the other hand, users are demanding higher capacity communication regardless of frequency. We will talk about AESA for aircraft, development results and issues at Ka band.
