发明名称 Multiband antenna using annular antenna elements on a substrate with different thicknesses
摘要 <p>A multi-band flat antenna that shows excellent radio characteristics in each of multiple different frequency bands. In a patch antenna, a plurality of flat antenna patterns for different frequency bands are formed on a dielectric substrate. The dielectric substrate has different plate thicknesses in each of the regions where the flat antenna patterns are formed. <IMAGE> <IMAGE></p>
