“…The characteristic impedances of the three ports are 50 Ω. To further improve the performance of the PD, the characteristic impedances of all the arms need to be optimised [27]. The PD is initially synthesised using the proposed method of calculating Z 0 and physical parameters w 1 , w 2 , g 1 , g 2 , l 3 , l 4 are optimised using HFSS.…”

In this study, a novel quasi‐transverse electromagnetic (TEM) transmission line (TL) on a single‐layer substrate is presented. The proposed structure comprises bilateral metalised vias and two longitudinal slots on the top and bottom plates, respectively. This two‐conductor TL separated by the two slots allows the quasi‐TEM mode and guarantees high isolation due to the vias which constrain the electromagnetic field. Additionally, the proposed structure provides a remarkable high range of the characteristic impedance, enabling a more flexible design. Furthermore, an empirical analytical formula is derived to calculate the characteristic impedance of the proposed TL adopting conformal mapping, and modified by a polynomial fraction. The transitions to the double‐sided parallel‐strip line and the microstrip line are proposed with which the propagation constant of this TL is extracted. The comparisons of the far‐end couplings of several types of microwave TLs have been provided by the simulation and measurement to verify the isolation property of the proposed TL. Finally, the proposed TL is applied to the T‐junction wideband power divider design to demonstrate its practicability. A prototype is fabricated and measured with a wide operating bandwidth from 6.8 to 17.6 GHz.

“…Diversos sistemas de rádio frequência (RF) e micro-ondas precisam de divisores de potência, por exemplo, alimentação de conjuntos de antenas [3], novas tecnologias de comunicação sem fio na faixa de 60 GHz [4], alimentação de elementos irradiantes em circuitos de camada dupla [5]. Além de serem amplamente aplicados, os divisores podem apresentar distintas formas geométricas e diferentes modelos teóricos, como divisor em formato de T [6], em formato de Y [7], anel circular [8], divisor do tipo Wilkinson [9], entre outros modelos. De modo geral, os divisores do tipo Wilkinson se apresentam como boas opções por possuírem boa isolação entre as portas de saída devido à utilização do resistor de 100 elas [1], [2].…”

Resumo Este artigo apresenta o projeto de um divisor de potência do tipo Wilkinson banda larga impresso e de dimensões reduzidas realizado no substrato FR-4 objetivando os serviços RFID e 5G. Os resultados, prático e simulado, mostram perda de transmissão de 3,5 e 4 dB, nas portadoras dos serviços desejados, além de um isolamento entre as portas de saída de 10 dB. Inclui também aplicações do divisor em sistema de transmissão full duplex e na alimentação de painel com antenas elípticas. Os resultados apresentados mostram um bom comportamento alcançando, em ambos os casos, até 160 MHz de largura de banda.
