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).

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, ...

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

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.
