Diversity antenna system for automobile

Abstract

Abstract PURPOSE:To decrease the disturbance to a visual field and to obtain the perfor mance of an excellent sensitivity characteristic and directivity or the like by adopting a transparent antenna being a transparent conductive film on a window glass of an automobile as an antenna element for at least one of plural anten nas. CONSTITUTION:In a diversity antenna system of an automobile, the transparent antenna being a transparent conductive film formed on a window glass of the automobile as an antenna element is adopted for at least one of plural antennas. For example, said transparent antenna is applied to both side window glasses 13a, 13b as the application to a diversity reception system, and side transparent antennas 17a, 17b of different shape are formed respectively to the side window glasses 13a, 13b. Then collectors 20a, 20b are provided to the side transparent antennas 17a, 17b.
