Abstract-NASA has been leading the Terahertz (THz) technology development for the sensors and instruments in astronomy in the past 20 years. THz technologies are expanding into much broader applications in recent years. Due to the vast available multiple gigahertz (GHz) broad bandwidths, THz radios offer the possibility for wireless transmission of high data rates. Multi-Gigabits per second (MGbps) broadband wireless access based on THz waves are closer to reality. The THz signal high atmosphere attenuation could significantly decrease the communication ranges and transmittable data rates for the ground systems. Contrary to the THz applications on the ground, the space applications in the atmosphere free environment do not suffer the atmosphere attenuation. The manufacturing technologies for the THz electronic components are advancing and maturing. There is great potential for the NASA future high data wireless applications in environments with difficult cabling and size/weight constraints. In this study, the THz wireless systems for potential space applications were investigated. The applicability of THz systems for space applications was analyzed. The link analysis indicates that MGbps data rates are achievable with compact sized high gain antennas.

“…Great advances in this area have without doubt been the major trigger of the actual THz technology expansion [34], [188]- [190]. It continues with the THz sources, a critical element that is still far from the desired level of performance and that, with the research nowadays, may hopefully give an important impulse to THz systems.…”

“…Direct systems are non-coherent and they detect only the signal amplitude. This feature is important from the point of view of the information available after detection, which directly influences in important detector parameters such as detector sensitivity and spectral resolution [34], [188]- [190]. The detectors are used in both detection systems are basically the same, but in some cases, some of them are not suitable for coherent systems due to their relatively long response time.…”

“…SBDs are widely used as detectors in the THz band, either in direct detection, or as nonlinear element in heterodyne receiver mixers, operating at temperatures ranging from cold 4 K to ambient 300 K [34,189,227,228]. During the 80s and early 90s cryogenically cooled SBDs were used in mixers preferably.…”

“…In spite of this fact, SIS mixers seem to be best solution for the ground-based radio-astronomy in the THz band for f < 1 THz. Compared to the previously described Schottky Barrier Diodes, SIS mixers demand much lower Local Oscillator (LO) power (µWs instead of mWs) [34].…”

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 ...
