A vehicle roof antenna comprises an insulating support 7 fixed perpendicularly with respect to an upper surface of a base plate 3 and a conductive plate antenna 8 having a surface angled with respect to a side surface of the insulating support 7, characterised in that at least one arm (62 64, 93, 94, figure 4) is provided to regulate a position of the conductive plate by contacting the insulating support 7. The arm may abut the insulating support 7 or may pass through the insulating support 7 and form a latch against the opposite surface. The insulating support 7 may be a circuit board substrate with an antenna pattern 18 connected to the conductive plate antenna 8. A plurality of conductive plates may be provided such as to form a roof or inverted-V shape. The conductive plates may be attached to an upper edge of the insulating support 7 using clamps or clips (23, figure 8). |
