dc.description.abstract The design of a circular aperture planar reflectarray at 9.4Ghz center frequency is presented in this thesis. For the first time, an aperture coupled cross shaped patch is used as a cell element for a reflectarray antenna. A full characterization of the novel element is presented in this research; this includes the phase curve, a frequency effect study, an incident angle study, a comparison with traditional reflectarray elements, calculation of dissipative losses, and cross polarization levels. The cross patch antennas are designed with the a Rogers RT 5880 substrate, the slots are made in the ground plane, and the stubs are implemented in a Rogers RO 3006 substrate. Rogers RT 5880 substrate has a thickness of 0.508mm and a relative permittivity of 2.2, the Rogers RO 3006 has a thickness of 0.64mm and relative permittivity of 6.15. The phase distribution needed for broadside radiation for an F/D of 1 is presented. The results for the design are presented and analyzed in the thesis. en_US
dc.description.abstract En esta tesis se presenta el diseño de una antena reflectarray de apertura circular centrada en la frecuencia 9.4Ghz. Por primera vez un parcho en forma de cruz acoplado por una abertura es usado como elemento base para el diseño de un reflectarray. Se presenta la completa caracterización del elemento en la Tesis. La caracterización incluye la curva de fase, las perdidas disipativas, los errores en frecuencia, el efecto del angulo incidente y el nivel de polarizacion cruzada. Los parchos en forma de cruz fueron diseñados con el substrato Rogers RT 5880 que tiene un espesor de 0.508 mm y una permitividad relativa de 2.2, los stub fueron diseñados usando el substrato Rogers RO 3006 que tiene un espesor 0.64 mm y una permitividad de 6.15. La de distribución de fase necesaria para irradiar en broadside es presentada en la tesis. Los resultados del diseño son presentados y discutidos. en_US
