Abstract
At least one filter block () is formed in a thin and flat dielectric multilayer structure () and fixed with radiation elements (). Each filter block includes at least one of a low-pass filter, a high-pass filter and a band-eliminating filter. On the surface (one major surface) side and/or the side face of the multilayer structure, at least one radiation element () being connected with the filter block is provided and feeding parts () for supplying signal to the radiation elements are provided on the rear surface of the multilayer structure. Consequently, the antenna and the filter block are integrated and a small surface mountable antenna with a built-in filter of a structure such that signals are not mixed each other even when signals of a plurality of frequency bands are transmitted/received can be obtained.
