Abstract
This paper presents an analysis of the shortcomings
of dipoles in space-based low frequency radio astronomy. It is at
these frequencies that it is expected to uncover more information
about the beginning of the universe, the Dark Ages. At this
moment there is a 5 m tripole setup, part of the Netherlands-
China Low Frequency Explorer (NCLE) on Earth-Moon-L2 Halo
Orbit. However, the dipole is limited in term of bandwidth,
size and impedance. To further increase the sensitivity, more
advanced structures are needed which can be packed in the
same volume. This paper will present multiple solutions to the
problem in the form of inflatable antennas and the usage of shape
memory alloys which are both viable options. A future solution
is a combination of both for packing efficiency and rigidization.
