“…Own to the dimensions of these unit elements, the inter‐element spacing of the planar aperture array will be larger than a wavelength; thus, this causes the grating lobes in the radiation pattern. The problem of the grating lobes solves using a grid configuration placed on horn apertures . Since the aperture dimensions of an aperture antenna will change the radiation pattern, its aperture size may be varied by a new parasitic structure to obtain a formal array factor.…”

In this letter, a 2 × 2 pyramidal horn antenna array is presented to accomplish linear and circular polarizations with suppressed grating lobes using removable grid cover structures (GCSs) mounted on the top of the antenna array. The spacing between the unit cells becomes farther than a wavelength due to electrically large pyramidal horns and the feeding network. The proposed GCSs, called linear and circular GCS, in this arrangement act as a spacing reducer between the apertures of the horn antennas without the need of physical change of the spacings. Thereby, the desired array factor with newly created apertures can be realized. Although using both GCSs benefit to suppress the highest‐level grating lobe, the circular GCS also converts the polarization to circular. The feeding network, which also prevents a formal array factor due to its massive structure, is made up of equal power dividers with T‐junction waveguides. The proposed horn arrays, the feeding network, and both GCSs are fabricated, and the total antenna is measured to validate the simulation results. A good agreement is achieved between simulations and measurements.

Abstract-A multilayer integrated diplexer-antenna array module for Ka-band high capacity point-to-point backhaul links is presented. The proposed module is composed of three unconnected metal layers with a simple mechanical assembly and no electrical contact requirements between the distinct layers based on gap waveguide technology. A 7 th order hybrid diplexersplitter with a novel architecture is successfully integrated into a ridge gap waveguide corporate distribution network of a 16 × 16 slot array antenna. The measured input reflection coefficients for both Tx/Rx channels are below -13 dB with measured total efficiency better than 60% in the designed passband. The measured isolation of gain between the two channels is more than 55 dB.

“…The most relevant example in the framework of this work is the latter one. This transition has been used several times, mainly to feed high-gain antennas ( [72], [75] and [165]- [167]) where the feeding is placed at the back of the antenna. By tuning a few parameters, both types of waveguides can be matched.…”

Just when you think you know all the answers, the universe changes all the questions." iv a todo el mundo. En cualquier minuto y siempre sin un pero. Es un placer haber viajado contigo, compartido aventuras en Londres, Paris, Boston...y haber aprendido tanto de ti. También a Nora y María, las chicas de la sala del GRE. Vosotras sois parte imprescindible de este trabajo, hemos crecido juntos. Muchas gracias por todos los momentos de distensión, las risas, por apoyarme con la tesis y también con el teatro.Mariano, Eva, Vicent M., Marta, Lorenzo, Juan, Felipe. Conoceros aún más y aprender de vosotros ha sido un privilegio. Gracias, además, por haberme permitido compartir docencia con vosotros. Han sido momentos para crecer tanto profesional como vitalmente.Gente que va y viene. Que de algún modo siempre está. Marc, Cristina, Alexia, Jaime, por supuesto Toni B. y Tomás. Que suerte haberos conocido y que pena no haber compartido más tiempo. Sois personas brillantes y con mucha luz, ojalá pudiera robaros algo de ese magnetismo que transmitís, y ojalá, de la manera que sea, volvamos a encontrarnos. A la familia de Ecuador: Fernando, Diana, Carlos, Daniel, Anibal. A la de Marruecos: Zakaria, Hamza, Yousra. A la de Argentina: Juan Pablo, Alberto, Guillermo y tantos otros que seguro que olvido. También parte de este trabajo ha sido posible gracias a Ashraf, Jian, Abbas, Sadegh y Jin Lin, que fueron un apoyo fundamental durante mi estancia en Chalmers University of Technology. A mi familia. A mis abuelos Rosita y Miguel, Amparo y Salvador. Sé que habéis estado conmigo.A mi hermana Nuria, por aguantar mil cenas oyéndonos hablar de Antenas.A mi madre, por apoyarme y espolearme. Por exigirme siempre más cuando yo creo que es suficiente.A mi padre, por ser un guía infatigable, porque llegar hasta aquí a tu lado es de las mejores cosas que haré en esta vida.A Dulce, la mujer más extraordinaria del mundo. Si existe el destino, hizo bien al ponernos juntos. Tu a mi lado y yo al tuyo para superar todos los obstáculos y superar todas las barreras. Nunca habrá suficientes gracias por haberme apoyado tanto y haber sido tan paciente y sincera en cada etapa de este viaje.Es curioso como al final de todo, de tanto trabajo, debería sentirme inmensamente feliz, pero echando la vista atrás, no soy más feliz ahora que durante todo el camino recorrido a vuestro lado. Gracias.x
