10.1: Radiación de cargas y corrientes
10.2: Antenas de dipolo corto
10.3: Ganancia de antena, área efectiva y propiedades del circuito
10.4: Matrices de Antenas
La mayoría de los servicios fijos, como los servicios punto a punto, difusión y satélite, se benefician de mayores ganancias de antena. Además, algunas aplicaciones requieren una dirección rápida del haz de la antena de un punto a otro, o incluso la capacidad de observar o transmitir en múltiples direcciones estrechas simultáneamente. Los arreglos de antenas con dos o más dipolos pueden soportar todas estas necesidades. Las matrices de otros tipos de antenas pueden aumentar de manera similar el rendimiento.
