The use of ceramic antennas is suitable for difficult environmental conditions in which it is difficult to transfer. The use of an antenna array can cause the radiation pattern is much more directive and make the transmission more efficient. It is also possible to modify the frequency and phase of the signal between elements of the array making it possible to change the direction of the radiation pattern without any mechanical movement. This combination is very often used in Synthetic Aperture Radar (SAR) are also suitable for small satellites or for applications on Earth. This final bachelor work is aimed at the design and implementation of an antenna to be implemented with synthetic aperture antenna for a femtosatellite. The development of the antenna is implemented through a software tool called EEsof Advanced Design System (ADS). The antenna will be deployed and tested in the laboratory to obtain the reflection coefficient, the gain and impedance versus frequency and check the results of actual tests are equal to those obtained in computer simulations. This final work try to see if this antenna can be used in a low-cost real mission where we must use a femto-satellite (mass less than 100 grams). The development will take place within the group WikiSat which is a competitor of the N-Prize to launch a femto-satellite in LEO at a cost less than £ 1,000.
