Abstract
Spacecraft and vehicular bodies often require antennas that are conformal to their surface. The advantage of this choice is that they do not suffer from air drag or breakage and can be formed into any desirable shape. We can make them to operate at those frequencies at which simple wire antennas will require considerably longer length. Our thesis is about conformal antenna design for two space projects. The first project involves an array of patch antennas placed on multi-layer cylindrical substrate. Four of these antennas are S-band and four of them are GPS-band antennas. The second project deals with the design of a slot antenna for 3U CubeSats. 3U CubeSat is a type of miniaturized satellite having a volume of 10cm × 10cm × 30cm. Our slot antenna operates in UHF band and saves a lot of space for integration of solar panels as well. We have presented solution strategies to achieve dual band operation, isolation between two slot antennas for uplink and downlink channels, circular polarization, and EMI shielding. At the end, the final model has been simulated and results have been discussed.
