“…Rotman formulations were performed and their methods adjusted according increasing applications. From the parallel plate lens developed by Rotman is possible to derive a formula for the microstrip Rotman lens including new parameters and concepts . According to the referenced literature, the important parameters defined from the microstrip Rotman lens shown in Figure are η=NɛrF w=ɛefɛr(WW0)F g=GF x=XF y=YF a0=cosα b0=senα a1=cosψ b1=senψ where ɛ r and ɛ ef are the relative dielectric constant of the substrate and the effective dielectric constant of the microstrip transmission line, respectively.…”

“…A partir da lente de placas paralelas desenvolvida por Rotman é possível derivar uma formulação para a lente de Rotman em "microstrip" incluindo novos parâmetros e conceitos [Hansen, 1991], [Wang et al, 2012]. Na Figura 10, pode-se observar que ângulo de feixe do "array" de antenas passa a ser ψ e que se torna diferente do ângulo focal α da lente.…”

“…As possíveis reflexões existentes em outros setores do núcleo da lente podem ser fatores de redução de desempenho. Uma solução bem simples para reduzir esses efeitos está em "fechar" o núcleo da lente com portas fantasmas terminadas com cargas de 50 Ω, que são casados utilizando também o "taper" linear [Musa e Smith, 1989], [Carlegrim e Pettersson, 1992], [Dong et al, 2008], [Wang et al, 2012].…”
