Multi-band antennas having enhanced directors therein that inhibit radiation interference across multiple frequency bands

An antenna, comprising:

• a first radiating element configured to emit first electromagnetic radiation in response to at least one feed signal having a frequency within a first radio frequency (RF) band;
• and
• a director positioned forwardly of the first radiating element and in a path of the first electromagnetic radiation, said director comprising a plurality of passive impedance elements that provide frequency-dependent reactances to currents induced within the director in response to the first electromagnetic radiation, said plurality of passive impedance elements including a primary capacitive element, a first series LC circuit electrically coupled to a first portion of the primary capacitive element, and a second series LC circuit electrically coupled to a second portion of the primary capacitive element.
