Abstract
An antenna includes a reflector, a radiating element extending forwardly of the reflector, and a director positioned forwardly of the radiating element. The director includes a plurality of passive impedance elements that provide frequency-dependent reactances to currents induced therein responsive to electromagnetic radiation generated by the radiating element. The plurality of passive impedance elements include: (i) a primary capacitive element, (ii) a first series LC circuit having a first inductor therein electrically connected to a first portion of the primary capacitive element, and (iii) a second series LC circuit having a second inductor therein electrically connected to a second portion of the primary capacitive element.
