Abstract
Consiste en un Proyecto de infraestructuras de telecomunicaciones, siendo el Mercado al que va dirigido el de los Fabricantes y Operadores de sistemas y redes de comunicaciones terrestres como áreas con el fin de ofrecer a Clientes o Propietarios o Fabricantes un tipo nuevo de antena. El objetivo principal se basa en el análisis, diseño y desarrollo de una antena transmisora en la banda de UHF para el nuevo Standard de Televisión digital DVB-T2 que acabará implantándose. Para ello es necesario hacer frente a la problemática existente que consiste en diseñar una antena de dos polarizaciones que se aloje en el mismo espacio que las actuales de polarización simple, es decir dos antenas en una. En España este tipo de antenas no está desarrollado todavía o por lo menos no se tiene constancia de ello. Uno de los posibles motivos es que se implantó apresuradamente el sistema DVB-T que no requería este tipo de soluciones, pero hay países, incluso en Europa donde se plantean pasar de la TV analógica a DVB-T2 directamente. En Estados Unidos hay algún modelo de antena parecida con unas especificaciones limitadas que imposibilitan su uso en Europa, en cuanto al ancho de banda de uso se refiere. Los objetivos que se plantean para la antena propuesta son los siguientes: - Ancho de banda: 470 – 860 Mhz - Polarización mixta o circular. - Ganancia 11 dBd. - VSWR menor que 1.15 (23 dB con red de alimentación) - Relación axial menor que 1.6 (4 dB) - Ancho de haz en el plano horizontal 65 grados y ancho de haz vertical 26 grados. ________________________________________________________________________________________________________________________
The project consists of a telecommunications infrastructure project, having as target the Manufacturers and System Operators and terrestrial networks areas in order to offer a new type of antenna to Customers, Owners and Manufacturers. The main objective is based on the analysis, design and development of a transmitting antenna in the UHF band for the new digital TV Standard DVB-T2 which will be finally implanted. This requires addressing the existing problem about to design doble polarization antenna staying in the same space as the single polarization. In Spain this type of Antenna is not developed yet or at least not aware of it. One possible reason is that the system DVB-T was implemented hurriedly and it did not require such solutions. There are countries, even in Europe where moving from analog TV to DVB-T2 directly. The U.S has a similar antenna, with limited specifications that preclude its use in Europe, in term of bandwidth. The main objectives for the proposed antenna are the following: - Bandwidth: 470 – 860 Mhz - Doble polarization. - Gain 11 dBd - VSWR below 1.15 (23 dB including feeder network) - Axial Ratio below 1.6 (4 dB) - Vertical plane beamwidth 62 grades and horizontal plane beamwidth 26 grades
