Abstract: A coupling device includes a plurality of couplers. Each coupler includes a transmission main line and a coupling subline. The transmission main line is used for providing an input end and an output end. The coupling subline is coupled with the transmission main line to provide two coupling ends. The coupling subline includes two first parts located on opposite sides of the transmission main line and a second part connected between the two first parts. The coupling sublines of the plurality of couplers are connected in series to provide a first coupling output port and a second coupling output port. The first part of the coupling subline of at least one of the plurality of couplers has a shared section with the second part of the coupling subline of an adjacent one of the plurality of couplers.

Abstract: A multi-band antenna includes a reflector, and a plurality of first radiating elements on the reflector. The plurality of first radiating elements are configured to radiate a first antenna beam(s) in a first frequency band responsive to at least one feed signal. A passive radiation-filtering element is provided, which extends proximate the first antenna beam(s). The passive radiation-filtering element includes at least one of a low-pass LC circuit, a band-pass LC circuit, and a highpass LC circuit therein, which is configured to provide a lower frequency-dependent impedance to radiation within the first frequency band relative to radiation at frequencies outside the first frequency band. The passive radiation-filtering element may be configured as a multi-segment fence having capacitive and inductive elements therein, which are electrically coupled in series.

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.
