At present, there is an active process of miniaturization of the whole space technology, including on-board equipment. On-board an-tenna-feeder devices also considered the process of miniaturization. Considering a number of the on-board antenna features, there is an actual, modern task of developing a small-sized, low-profile, reliable, simple and high-tech antenna system for small satellites. In this paper the variants of using different parts of spacecraft such as solar battery and gravitational bar as on-board antenna have been presented. The models of antenna-solar battery and antenna-gravitational bar developed with using of computer-aided design program MMANA have been presented. The models parameters of the primary interest such as antenna impedance and radiation pattern have been evaluated. These results show the possibility of using these variants in practice. Also the variant of the miniaturization of a dipole has been presented.
