(54)Communications structures including antennas with filters between antenna elements and ground sheets


(57) A communications structure (101) may include a ground sheet (119), a feed conductor (105d), and an active antenna branch (105a) electrically coupled to the feed conductor (105d). A parasitic antenna branch (105b') may be electrically coupled to the ground sheet (119), and the active and parasitic antenna branches (105a, 105b') may be spaced apart. Moreover, the parasitic antenna branch (105b') may be between portions of the active antenna branch (105a) and the ground sheet (119).
