High Compaction Ratio Antenna

The HCR antenna is designed for high-frequency, high-gain antenna performance up to 40 gigahertz.

The HCR antenna has a fast production turnaround that supports smallsat constellation development.

L3Harris applies fabrication and surface-shaping processes that are based on 40 years of reflector heritage to streamline production and minimize development risk for our customers.


L3Harris has been engineering first-of-their-kind payloads that meet and exceed the needs of our customers for more than 50 years. Our position as the most experienced unfurlable mesh reflector manufacturer in the world has been earned by continually pushing the boundaries of space antenna technology. Today, we are the number-one provider of large high-accuracy mesh reflectors, with more than 90 antennas on orbit.

By drawing upon this experience and our repeatable designs, proven processes and rigorous testing capabilities, we reduce risk for our space antenna customers, who want to tap the potential of smallsats for their communications missions.
