Voyager High-Gain Antenna (HGA) schematic. Note the Cassegrain optics, as well as the frequency-selective subreflector that’s transparent to S-band (2.3-GHz) but reflects X-band (8.4-GHz).

a wide frequency band and high gain and can realize large angle beam scanning. Compared with the metasurface, the ...

That gusher of findings will include new observations of exoplanets—or planets orbiting other stars; new surveys of the structure of the Milky Way; and new studies of dark energy, the mysterious, ...

thanks to its high gain and efficiency. Operating in the -40 °C to +85 °C temperature range, the antenna boasts IP67 protection after installation and is both RoHS and REACH compliant.
