Abstract
This invention relates to an antenna (1) of the type comprising a casing (3) having a reflector (5) defining a slot (7). The antenna (1) further comprises a PCB (9) carrying a plurality of radiating elements (11) and a feed harness (42) comprising a plurality of feed tracks (43). There is provided a phase shifting device (47) to electronically tilt the antenna. The phase shifting device (47) comprises a stub (117) that is preferably extensible in length to provide a number of tilt options. A plurality of stub branches (121) may be connected to the stub (117) to vary the length of the stub. The phase shifting means is further preferably mounted on a separate daughter PCB board (111, 140) either perpendicular to or parallel to the mother PCB (9). In this way, a more compact phase shifting arrangement may be provided and furthermore the existing antenna casings may be used. <Figure 3>
