Table 1. Comparison of various types of spaceborne deployable mesh antennas

Factor	AstroMesh Type	Wrapped-Rib Type	Foldable Type
Config.
Pros.	♦ Good surface accuracy♦ Easy deployment speed adjustment♦ Suitable for large antenna	♦ Simple deployment mechanism	♦ Easy deployment speed adjustment♦ Medium surface accuracy (dependent on number of ribs)
Cons.	♦ Low reliability (Complex mechanism and many joints)♦ 0g device required	♦ Large deployment shock♦ Possible to Mesh surface damage when deployment	♦ Relatively more complex than Wrapped-Rib type♦ Ground support equipment such as zero-g device required (for large antenna)
Properties	♦ Off-axis antenna	♦ Horn-feed parabolic antenna or Cassegrain/Gregorian antenna	♦ Horn-Feed parabolic antenna or Cassegrain/Gregorian antenna
