Abstract
An antenna includes 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. A director is provided, which is positioned forwardly of the first radiating element, and in a path of the first electromagnetic radiation. The director includes first and second passive impedance elements that provide respective first and second frequency-dependent reactances to first currents induced within the director in response to the first electromagnetic radiation. The first and second passive impedance elements may include a first inductor and a first capacitor, which are electrically coupled in series. The director may also be configured to include a plurality of passive impedance elements that are connected within an impedance loop containing a second LC circuit in series with a first LC circuit.
