Abstract
An antenna radiator assembly (200) and radio communications assembly (1) comprising a circuit board (210) supporting electrical conductors (225), one of the electrical conductors (225) being coupled to a feed point (130), and the circuit board (210) having a ground plane (140) formed from at least one conductive sheet. There is a tuning resonator (132) comprising a tuning plate (310) operatively coupled to a tuning line (320), the tuning plate (310) being formed from part of the conductive sheet. An antenna radiator element (107) is spaced from said circuit board (210) and coupled to the feed point (130), and when viewed in plan view there is an overlapping area where an overlapping surface area of the antenna radiator element overlaps an overlapping surface area of the circuit board thereby forming a sandwiched dielectric region therebetween. A ground connector inductively couples the antenna radiator element (220) to the ground plane (140), wherein the tuning resonator (132) is disposed in the overlapping surface area.
