Abstract: The present disclosure relates to a printed circuit board assembly, which includes: a first printed circuit board, printed with a first transmission trace; a second printed circuit board, printed with a second transmission trace; a substrate, in which, the provides a through aperture for a radio frequency connector; and a radio frequency connector, which includes an inner contact portion, an housing and an insulating part provided between the inner contact portion and housing, where the radio frequency connector is configured to be received in and pass through the through aperture, such that a first end of the inner contact portion of the radio frequency connector is electrically connected to the first transmission trace and a second end thereof is electrically connected to the second transmission trace, so that a first end of the housing of the radio frequency connector is electrically connected to a ground layer of the first printed circuit board and a second end thereof is electrically connected to the ground layer of the second printed circuit board. Thus, the printed circuit board assembly is capable of improving aspects such as shielding effects, PIN performance and/or degree of integration compared with prior art.

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.

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 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.
