Abstract

EL OBJETO DE ESTA PATENTE ES UN NUEVO TIPO DE ANTENA PLANA DE MICROONDAS APTA PARA TRABAJAR EN POLARIZACION LINEAL O CIRCULAR, LIBRE DE SOLDADURAS Y POTENCIALES FLOTANTES, POR LO QUE ESTA LIBRE DE DESCARGAS ELECTROSTATICAS Y DE PROBLEMAS DERIVADOS DE PRODUCTOS DE INTERMODULACION PASIVOS, TENIENDO ESPECIAL IMPORTANCIA SU APLICACION EN AERONAUTICA Y AMBIENTE ESPACIAL. ESTA ANTENA CONSISTE EN LA INTERCONEXION DE UN RADIADOR MICROBANDA CON UNA ANTENA ESPIRAL DE HILOS. PARA CIERTAS APLICACIONES, EN LAS QUE DICHOS RADIADORES SE DISPONEN EN UN MISMO PLANO, PUEDE POTENCIARSE EL EFECTO RADIANTE DEL PARCHE, REDUCIENDO EL TAMAÑO DE LA ESPIRAL, CON LO QUE EL RADIADOR OBJETO DE ESTA PATENTE DE DEGENERA EN UNA RENDIJA CIRCULAR REALIZADA EN EL PLANO DE MASA DE LA LINEA DE ALIMENTACION, Y DONDE LOS HILOS, DISPUESTOS EN FORMA ESPIRAL, PROPORCIONAN CONTACTO ELECTRICO ENTRE LOS BORDES DE LA RENDIJA.
