The reflecting units are arranged separately from each other on the substrate and surrounding the antenna unit. The reflecting units are configured to adjust a radiation pattern of the antenna unit, and each of the reflecting units includes a first portion and a second portion. The first portion has an upper side and a lower side, and the lower side of the first portion is coupled to the substrate. The second portion has a lower side connected to the upper side of the first portion. A width of the lower side of the first portion is smaller than a width of the lower side of the second portion.

An antenna array for use in a passenger vehicle. Four of the roof support pillars are used as antenna elements. Each of the four pillars is electrically connected or coupled to one end of a corresponding meanderline component. The other end of each meanderline is in turn coupled to a radio receiver, typically through a combining network.
