Abstract: An antenna radiator assembly (201) and radio communications assembly (200) comprising a circuit board (210) supporting electrical conductors, at least one of the electrical conductors being coupled to a feed point (130). There is a ground plane (140) with a first planar element (141) and a second planar element (142), the first planar (141) element being supported by the circuit board (210) and having a first planar element plane (240) parallel to a surface (250) of the circuit board (210), and the second planar element (142) having a second planar element plane (245) lateral to the first planar element plane (240). A ground connector is coupled to the ground plane (140) and the antenna radiator element (107) is coupled to both the ground connector and the feed point. The antenna radiator element (107) is spaced from the ground plane the antenna radiator element (107) has an antenna radiator element plane (295) is lateral to the first planar element plane (240).
