O guia de ondas pós-parede com uma matriz linear de pares de slots com cancelamento de reflexão e alimentação central é projetado para cancelar a inclinação dependente da frequência do feixe principal e aumentar a largura de banda do ganho de visão da antena. A matriz é alimentada no centro do guia de ondas pela parte traseira; o comprimento do guia de ondas radiante é reduzido pela metade e o efeito de linha longa na operação de ondas viajantes é suprimido. Os autores estabelecem o procedimento de projeto de array em etapas separadas para reduzir a carga computacional na otimização iterativa usando o simulador Ansoft HFSS. Um arranjo linear de alimentação central, bem como um equivalente de alimentação final com excitação uniforme, é projetado para operação em 25.6 GHz e medido. Os desempenhos medidos confirmam o design e a vantagem da alimentação central; um feixe de mira independente de frequência é observado e a largura de banda de frequência para redução de ganho de 3 dB é aumentada em 1.5 vezes em comparação com a matriz de alimentação final.

Abstract: Post-wall waveguide with a linear array of reflection-canceling slot pairs and center-feed is designed to cancel the frequency dependent tilting of the main beam and enhance the bandwidth of the antenna boresight gain. The array is fed at the center of the waveguide from the backside; the length of the radiating waveguide is halved and the long line effect in traveling wave operation is suppressed. Authors establish the array design procedure in separate steps to reduce the computational load in the iterative optimization by using Ansoft HFSS simulator. A center-feed linear array as well as an end-feed equivalent with uniform excitation is designed for 25.6 GHz operation and measured. The measured performances confirm the design and the advantage of the centre-feed; a frequency independent boresight beam is observed and the frequency bandwidth for 3 dB gain reduction is enhanced by 1.5 times compared to the end-feed array.
