Abstract
This paper describes test methods to verify natural frequencies of deployable satellite antennas. We clarify the effect of weight reduction of reflectors on test methods to verify antenna frequencies. Two test methods are considered to verify antenna frequencies. One is vibration tests commonly used and the other is mass property tests. When the reflector can be assumed to be rigid from analytical results, the latter is effective for frequency verification. A numerical example shows that weight reduction of deployable satellite antennas have a little effect on test selection to verify natural frequencies of the antennas.
