Abstract

Una antena de red planar (10) con una matriz de conmutación (14) que acopla una señal de radiofrecuencia (RF) con dos alimentaciones de líneas de exploración con ferritas distribuidas (12, 13) que alimentan a una antena de red corta transversal continua planar (11). Las alimentaciones de líneas de exploración acoplan energía de RF con la antena desde lados opuestos para formar un total de cuatro haces desfasados en el espacio que cubren, cada uno, diferentes sectores angulares de exploración. La antena tiene complejidad reducida y menores costos de diseño y producción. El uso de alimentaciones de líneas de exploración con ferritas dobles, la matriz de conmutación y la antena corta transversal continua para obtener una exploración con gran ángulo proporciona un comportamiento importantemente mejorado. El presente invento utiliza las dos alimentaciones de líneas de exploración con ferritas distribuidas para obtener mayor cobertura de exploración a frecuencias de ondas milimétricas superiores,en las que los materiales ferríticos practicables son menos activos y proporcionan una capacidad disminuida de exploración. Las alimentaciones de líneas de exploración y la antena de red planar se pueden diseñar de manera tal que los cuatro sectores de exploración sean contiguos, para aumentar la cobertura de exploración angular de la antena. La matriz de conmutación se utiliza para alimentar consecutivamente a cada uno de cuatro puertos de RF, lo que produce de manera efectiva un único haz que explora por los cuatros sectores contiguos de exploración.
