Resumo: | This dissertation presents the development of two radio frequency (RF) devices for fifth-generation mobile networks (5G), namely: an ultra-wideband Vivaldi antenna and a RF phase shifter. The proposed Vivaldi antenna is based on a three-dimensional structure with magnetic dipoles and aluminum plates to improve the impedance matching bandwidth in the lower frequency range. Additionally, the corrugation technique was applied to improve the impedance matching around 15.0 GHz. 3D printing and machining of aluminum plates were used in the manufacturing process. In general, there is excellent agreement between numerical and experimental results. The antenna presented bandwidth from 0.59 to 26.0 GHz, performed 191.12% fractional band. The final antenna dimensions were 0.190??max x 0.229??max x 0.129??max, where ??max is the wavelength of the bandwidth lowest frequency. It was obtained measured gains good agreement with simulated results. Measured gain of 2.15 dBi at 0.75 GHz, 7.09 dBi at 1.80 GHz, 4.09 dBi at 2.10 GHz, 6.69 dBi at 3.50 GHz, 8.17 dBi at 10.0 GHz and 8.44 dBi at 26.0 GHz. The RF phaser shifter was based on metamaterials and designed to operate in the millimeter-wave band, including FR2 of the 5G New Radio (5G NR). More specifically, the RF phase shifter provides low insertion loss, due to the use of a metamaterial cell, whose propagation vector, electric field, and magnetic field form a left-handed triad (left handed (LH)) and a right-handed triad ( right handed (RH)). In addition, beam steering for millimeter-wave applications is performed using a Varicap diode. The phase shifter performance was numerically evaluated, as a function of the reflection coefficient, insertion loss, and phase variation. It was achieved insertion loss below 4.27 dB and a phase shift of 44.11?? varying by 10??. The phase-shifter is capable of operating in the range of 24.00 to 25.73 GHz with a reflection coefficientbelow -10 dB. |

A antena Vivaldi proposta e base- ada em uma estrutura tridimensional com dipolos magn??ticos e placas de alum??nio para melhorar o casamento de imped??ncia na faixa inferior de frequ??ncia da banda. Adicionalmente, aplicou-se a tecnica de corruga????o para melhorar o casamento de im- ped??ncia em torno de 15,0 GHz. No processo de fabrica????o, foi utilizado impress??o 3D e usinagem de placas de alum??nio. De modo geral, observou-se ??tima concord??ncia entre os resultados num??ricos e experimentais. A antena apresentou uma faixa de opera????o de 0,59 a 26,0 GHz, resultando em 191,12% de banda fracion??ria. As di- mens??es finais da antena proposta foram de 0,190 ?? ??max x 0,229??max x 0,129??max, onde ??max e o comprimento de onda para a menor frequ??ncia da faixa de opera????o. Obteve- se ganho de 2,15 dBi em 0,75 GHz, 7,09 dBi em 1,80 GHz, 4,09 dBi em 2,10 GHz, 6,69 dBi em 3,50 GHz, 8,17 dBi em 10,0 GHz e 8,44 dBi em 26,0 GHz. O defasador de RF foi baseado em metamateriais e projetado para operar na faixa de ondas milim??tricas, incluindo faixa de frequ??ncia 2 ( frequency range 2, FR2) do padr??o 5G New Radio (5G NR). Mais especificamente, o defasador de RF prove baixa perda de inser????o, em raz??o do uso de uma c??lula metamaterial, cujo o vetor de propaga????o o campo el??trico e o campo magn??tico formam uma tr??ade de m??o esquerda ( left handed (LH)) e uma tr??ade de m??o direita ( right handed (RH)). Al??m disso, o dire- cionamento de feixes para aplica????es em ondas milim??tricas ?? realizado empregando diodo Varicap. A analise num ?? erica de desempenho do defasador e realizada em fun????o do coeficiente de reflexao, perda de inser????oo e varia????oo de fase. Alcan??ou-se como resultados, perda de inser????o abaixo de 4,27 dB e uma varia????o de fase de 44,11?? va- riando em 10??. O defasador e capaz de operar na faixa de 24,00 a 25,73 GHz com coeficiente de reflexao abaixo de -10 dB.Submitted by Tede Dspace (tede@inatel.br) on 2021-11-25T16:01:26Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Antena vivaldi de faixa ultra larga e defasador de RF.pdf: 20677357 bytes, checksum: fff4b6b16f5aee0da52acf4e2c9d9ea8 (MD5)Made available in DSpace on 2021-11-25T16:01:26Z (GMT).

This dissertation presents the development of two radio frequency (RF) devices for fifth-generation mobile networks (5G), namely: an ultra-wideband Vivaldi antenna and a RF phase shifter. The proposed Vivaldi antenna is based on a three-dimensional structure with magnetic dipoles and aluminum plates to improve the impedance matching bandwidth in the lower frequency range. Additionally, the corrugation technique was applied to improve the impedance matching around 15.0 GHz. 3D printing and machining of aluminum plates were used in the manufacturing process. In general, there is excellent agreement between numerical and experimental results. The antenna presented bandwidth from 0.59 to 26.0 GHz, performed 191.12% fractional band. The final antenna dimensions were 0.190??max x 0.229??max x 0.129??max, where ??max is the wavelength of the bandwidth lowest frequency. It was obtained measured gains good agreement with simulated results. Measured gain of 2.15 dBi at 0.75 GHz, 7.09 dBi at 1.80 GHz, 4.09 dBi at 2.10 GHz, 6.69 dBi at 3.50 GHz, 8.17 dBi at 10.0 GHz and 8.44 dBi at 26.0 GHz. The RF phaser shifter was based on metamaterials and designed to operate in the millimeter-wave band, including FR2 of the 5G New Radio (5G NR). More specifically, the RF phase shifter provides low insertion loss, due to the use of a metamaterial cell, whose propagation vector, electric field, and magnetic field form a left-handed triad (left handed (LH)) and a right-handed triad ( right handed (RH)). In addition, beam steering for millimeter-wave applications is performed using a Varicap diode. The phase shifter performance was numerically evaluated, as a function of the reflection coefficient, insertion loss, and phase variation. It was achieved insertion loss below 4.27 dB and a phase shift of 44.11?? varying by 10??. The phase-shifter is capable of operating in the range of 24.00 to 25.73 GHz with a reflection coefficientbelow -10 dB. |
