ANTENNA INCORPORATING FILTER

Document Type and Number:

WIPO Patent Application WO/2002/067379

Kind Code:

A1

Abstract:

At least one filter block (25, 35, 45) is formed in a thin and flat dielectric multilayer structure (21) and fixed with radiation elements (2, 3). 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 (2, 3) being connected with the filter block is provided and sections (28, 38, 48) for supplying power 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 incorporating a filter and arranged such that signals are not mixed each other even when signals of a plurality of frequency bands are transmitted/received can be obtained.
