  • Communications assembly and antenna radiator assembly
    Patent number: 7436365
    Abstract: A radio communications assembly (200) and an antenna radiator assembly (201). The antenna radiator assembly (201) forms part of the radio communications assembly (200) and is housed in a housing (202, 203). The antenna radiator assembly (201) has a circuit board (210) supporting electrical conductors (225) one of which is coupled to a feed point (130). There is also a ground plane (140) and an antenna radiator element (107) is coupled to the feed point (130). The antenna radiator element (107) is spaced from the ground plane (140) and a tertiary antenna radiator arm (155) spaced from the antenna radiator element (107). There is also a first band stop filter (150) disposed in a space (212) between the tertiary antenna radiator arm (155) and the antenna radiator element (107). The first band stop filter (150) provides electrical coupling of the antenna radiator element (1070 to the tertiary antenna radiator arm (155) at its band pass frequencies.
