Abstract

Expendable structures are quite attractive for large antennas erected in apace as they are lightweight, can be packaged in a limited space for launch, and can be readily deployed upon command. The two antenna configurations presented in this paper are examples of what can be accomplished.
The 100 foot diameter parabolic dish and the 70 toot long helix antenna were chosen as being the representative – the size being dictated by such considerations as frequency range, antenna gain characteristics, and power requirements.
The thermal analysis and stress analysis of the antennas will not be investigated in this paper as they are quite lengthy. The structural design requirements will be noted. The weight analysis will be treated in detail which will include material selection and sizes. The deployment schemes for the two configurations will be discussed.
It should be noted that the two configurations presented here are not the only antenna shapes available and that other deployment schemes are possible also.
