<p>Antennas and solar cells compete for limited available surface in satellite space crafts. An appropriate combination of the two can save valuable 'real estate'. This novel hybrid technology where amorphous silicon (a-Si:H) solar cells are either integrated or physically combined with printed slot . antennas is presented. This basic idea is demonstrated with the help of two innovative designs where the solar cells are directly grown on a stainless steel ground-plane or glued onto a standard copper layer printed on a dielectric substrate. To show the compatibility of solar cells and antennas, the concept is used to create a linearly polarized slot antenna, a circularly polarized slot antenna and a slot array. This concept offers advantages in terms of surface coverage, volume, weight and electric performance when compared with a simple juxtaposition of antennas and solar cells.</p> |
