Abstract
The motivation of this thesis has been to provide new advances on the design of multi-frequency and multi-beam reflectarray antennas with application to multiple spot beam satellites in Ka-band. In this respect, the thesis can be divided into two main parts. The first part contains the description of a novel reflectarray cell to operate in dual-linear polarization (dual-LP) at two separate frequencies (enabling independent phasing in each polarization and frequency), as well as the design of dual-band reflectarrays to provide independent beams in each polarization at both frequency bands. The second part of the thesis comprises the development of a bifocal design technique for dual reflectarray and dual transmitarray configurations, and its application to the design of multi-beam antennas in Ka-band. The aim of the bifocal technique is twofold, to improve the multi-beam performance of the antenna and to provide a certain degree of reduction on the angular separation between adjacent beams for a multi-spot coverage from a satellite.
