BALL GROUND, Ga. – The global demand for broadband connectivity has created a new generation of high throughput satellites in geosynchronous earth orbit (GEO), medium earth orbit (MEO) and now low earth orbit (LEO). Microwave and RF reports. Continue reading the original article

February 2, 2021 – However, technological innovation in the ground segment is struggling to catch up with the space segment – especially when it comes to developing the most elusive of all antennas: those that are inexpensive and electronically controllable – these next-generation, low-orbit satellite networks.

Electronically controllable antennas (ESAs), often referred to as flat screens, are the crucial link for next-generation constellations. Flat panel antennas offer greater efficiency and performance compared to their bulkier mechanical cousins, but are modular and dynamically steerable – all of this is needed for the future ground segment.

Antennas from NXT Communications Corp. (NXTCOMM) of Ball Ground, Ga., Leverage fragmented aperture technology that is the result of decades of defense research and collaboration with its technical research partner, the Georgia Tech Research Institute in Atlanta. The company’s phased array antenna design focuses on more efficient radiating elements to improve the portion of the antenna facing the satellite.
