摘要： 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.

摘要： 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 high-pass 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.

摘要： A patch radiating element that includes a feeder pillar and a patch radiator mounted on the feeder pillar. The patch radiator includes a first patch portion extending in a first direction and a second patch portion extending from an outer end portion of the first patch portion in a second direction. The second direction is different from the first direction. As a result, a space interval between adjacent patch radiating elements can be increased, thereby improving the isolation between the adjacent patch radiating elements so that beamforming of an antenna can be optimized.
