“…The most pursued designs have been those related with Slot Array Antennas (SAAs) [796], [802]- [820], some of them implementing advanced phased array configurations [802]. However, other topologies such as horns [821], RGW fed microstrip patch antennas [822], leaky-wave antennas in different configurations [823]- [824], or Rotman lenses [825]- [826] are as well found in the literature.…”

To my parents, brother and sister."Success is peace of mind which is a direct result of self-satisfaction in knowing you made the effort to become the best of which you are capable."Jonh Wooden "Lo que con mucho trabajo se adquiere, más se ama." Aristóteles AgradecimientosLa realización de esta tesis ha implicado no pocos años de trabajo y esfuerzo. Durante este importante periodo de mi vida han sido muchas las personas han estado a mi lado, brindándome su apoyo, ayuda, cariño y amor. Ya sea de una forma u otra, todas estas personas han contribuido a que este trabajo haya sido posible dando como fruto esta tesis. A todos ellos, me gustaría dedicarles un agradecimiento muy especial de todo corazón.Sin duda alguna, debo dar las gracias en primer lugar a mi director de tesis Mariano Baquero. Mariano, has sido un padre para mí profesionalmente hablando. Te conocí como alumno en las clases de Microondas, en las cuales me abriste la puerta a un conocimiento que me fascinó.Recuerdo perfectamente cuando fui a verte para preguntarte si podrías dirigirme el Proyecto Final de Carrera, y desde ese año 2009 hemos estado trabajando juntos. Quiero agradecerte no sólo haberme dado la oportunidad de trabajar en cada momento en elárea que más me ha gustado, sino el haberte preocupado por mí a nivel personal, velando siempre por mis intereses, ayudándome a desarrollarme personal y profesionalmente. Extiendo en este sentido mi agradecimiento a Miguel Ferrando. Si Mariano es el padre, tu serías sin duda el abuelo. Sin tu ayuda, la beca para la realización de esta tesis y los proyectos que han respaldado la misma no hubieran sido posibles. Tu esfuerzo ha permitido que el Grupo de Radiación Electromagnética (GRE) esté hoy dónde esta y que sus miembros nos beneficiemos de un entorno de trabajo excelente, produciendo trabajo de calidad. Debo agradecerte también tus siempre innovadoras ideas, algunas de las cuales se han convertido en una realidad plasmada en esta tesis.Una mención especial merece Daniel Sánchez. Dani, aunque tu nombre no figure como co-director bien sabes que podría estarlo. Jamás podré agradecerte lo suficiente la ayuda que me has prestado. Cuántas horas dedicadas a enseñarme en un sin fin de aspectos sin esperar nada a cambio, apoyándome también en los momentos difíciles, siempre presentes en una tesis. Bien sabes que lo mismo has hecho con cada uno tus compañeros, por eso eres el pilar del GRE Dani.Otra persona a la que estoy muy agradecido es a Vicente Boria. Tu activa colaboración en la dirección de esta tesis ha sido indispensable para la consecución de los resultados más relevantes de la misma. Sugeriste muy acertadamente una estancia en la Queen's University of Belfast, y me abriste la puerta a nuevas líneas de investigación en las cuales seguimos trabajando actualmente. Gracias por preocuparte por mi a nivel profesional y personal.En elámbito anterior, extiendo los agradecimientos a todo el GRE. It is also very important for me to acknowledge Prof. Vince Fusco. Thank you for hosting me in your group in Belfast ...

E-plane sectoral horn antenna based on printed ridge gap waveguide (PRGW) technology is designed for 5G applications. It is implemented on the top plate of the PRGW structure to avoid the losses and dispersion associated with conventional feeding mechanisms. The quasi-transverse electromagneticPRGW-based antenna is excited through a planar microstrip transition. First, the single horn antenna element is introduced with the microstrip feeding section. It shows an impedance bandwidth of fractional bandwidth 26% from 45.7 to 55.4 GHz with the realized gain of 12.7 dBi and radiation efficiency of 90%. In order to maximize the realized gain, a four-element linear horn array is introduced. The same impedance bandwidth is maintained with the array having a gain of 18.6 dBi from 45.7 to 55.4 GHz. The overall antenna array performance in the entire operating frequency range is stable with a radiation efficiency around 85%. Three matching sections are implemented to achieve better impedance matching. One is used to match the horn with the feeding aperture via the PRGW line. Another section is designed to match microstrip transition with PRGW ridge. Finally, two-stage quarter wavelength transformers are required to match the power divider with the array feeding network. A prototype of single-element horn antenna was fabricated to verify the concept of the design. Simulated and measured results show that the proposed antenna can operate in the frequency band of 45–55 GHz with good agreement of radiation performance. Moreover, the proposed designs are implemented and simulated using two microwave simulation tools (CST and HFSS) to verify the radiation performance, which exhibits good agreement. The design of an E-sectoral horn antenna and its array with high gain based on PRGW is demonstrated for the first time which is considered a novel issue. It can be integrated with other passive and active elements in communication systems. Thus, it can be a valuable component in 5G communication due to its high gain, compact size and ultra-wide band.
