Book excerpt: This project describes the process of design and manufacturing of an X-Band (7.1-8.5 GHz) antenna for a CubeSat satellite, facing many of the design criteria and challenges of pico-satellites. A CubeSat is a type of miniaturized satellite for space research that is made up of multiples of 10×10×10 cm cubic units and has a mass of no more than 1.33 kilograms per unit. It can be manufactured using commercial off-the-shelf (COTS) components for its electronics and structure. Limited size, low mass, circular polarization, high gain and wide bandwidth are the main challenges of the antenna design. A design of an aperture-coupled patch antenna has been performed to overcome the difficulties and fulfill all the requirements for CubeSats antennas. The antenna consists of one or two rectangular patches, fed by a microstrip line through a crossed slot in the ground plane. The two patches are separated from the ground plane using a layer of hard, low-permittivity foam. After the study of several antenna models, a stacked patch antenna (two patches) accomplished most of the requirements. The antenna models have been simulated using a 3-D electromagnetic simulation software, HFSS. Simulation and measured results show a gain within 6-10dB, very good circular polarization, a good matching in the whole frequency band and accomplish dimension criterias for CubeSat antennas.
