An integrated vehicular antenna system utilizes a dielectric panel with printed metallic regions on one or both sides thereof. In the form of the antenna in which the metallic regions are on both sides, on one side is formed a series of antenna elements as well as a series of transmission lines each extending from a respective antenna element to one of several signal connection points. A conductive layer is formed on the other side of the panel and extends from one edge of the panel, being positioned such that none of the antenna elements are within a projection it forms on the one side of the panel. However, some of the transmission lines are extended within the projection of the conductive layer in their passage from respective antenna elements to the signal connection points. This arrangement allows an antenna element on one end of the panel to be connected to a signal connection point on the other end of the panel while also allowing control to be maintained over the radiation pattern formed by that antenna element. Another form of the antenna has the conductive layer on the same side of the panel as the transmission lines. In that case, each transmission line extends in a respective channel formed in the conductive layer. Some of the connection points can be grouped together. |
