Abstract
Good electric characteristics are obtained even after an antenna being further incorporated into an antenna apparatus including an antenna case having a limited space. An antenna deviceis formed on an antenna substrateinstalled upright in an antenna base. A flat antenna unitis fastened to the antenna baseso that the flat antenna unitis immediately below the antenna device. If the wavelength of a center frequency in an operating frequency band of the flat antenna unitis λ, an interval between an upper surface of the flat antenna unitand a lower end of the antenna deviceis set to about 0.25 λ or more. Accordingly, it becomes possible to make directional characteristics of radiation in a horizontal plane of the flat antenna unitnon-directive without being affected by the antenna deviceand also to achieve good gain characteristics.
