A panel array and associated deployment system may include a first cable extending along a first row of panels and coupled to each panel of the first row of panels. The array and system may further include a second cable extending along a second row of panels and coupled to each panel of the second row of panels. The array and system may also include a first column of panels comprising a panel from the first row of panels and a panel from the second row of panels. The system may further include a spool positioned adjacent the first column of panels. The spool may be coupled to at least one of the first cable and the second cable and configured to apply tension to the first cable and/or the second cable.

Deployable panel array and related assemblies and methods

A planar reflectarray system provides for bandwidth broadening by employing a tunable (amplitude and phase) feed array. The tunable feed array is adjustable in amplitude and phase to compensate for aberrations by enabling feed re-focusing and field matching. The techniques modestly increase the size of the feed array and use active tuning to effectively correct for de-focusing when operating reflectarrays at frequencies away from the tuned center frequency.
