Uma nova antena de guia de ondas com fenda de ondas milimétricas é desenvolvida para sistemas de radar automotivos. Uma estrutura de antena adequada para produção em massa é proposta neste artigo. O guia de ondas é composto por duas partes; uma placa superior e uma placa inferior. Não é necessário entrar em contato próximo porque eles estão divididos no centro da parede larga do guia de ondas, onde a corrente elétrica é pequena. Além disso, os lóbulos da grade são suprimidos pelo uso de uma cavidade cilíndrica ao redor de cada fenda e pelo controle do arranjo da fenda sem o uso de material dielétrico no guia de ondas. Fabricamos a antena proposta por moldagem por injeção de metal. A eficiência medida da antena resulta em 55%, o que é bastante alto em comparação com qualquer outra antena convencional de ondas milimétricas de baixo custo. Essa eficiência é quase a mesma da antena fabricada por usinagem de metal de precisão. Neste artigo confirma-se que a antena proposta poderia ser fabricada com baixo custo.

Abstract: A novel millimeter-wave slotted waveguide array antenna is developed for automotive radar systems. An antenna structure suitable for mass-production is proposed in this paper. The waveguide is composed of two parts; an upper plate and a bottom plate. It is not necessary to contact each other closely because they are divided at the center of the broad wall of the waveguide where the electric current is small. In addition, grating lobes are suppressed by using a cylindrical cavity around each slot and by controlling the slot arrangement without using dielectric material in the waveguide. We have fabricated the proposed antenna by metal injection molding. The measured antenna efficiency results in 55%, which is quite high in comparison with any other conventional low cost millimeter-wave antenna. This efficiency is almost the same as that of the antenna fabricated by precision metal machining. In this paper, it is confirmed that the proposed antenna could be manufactured with low cost.
