    摘要: A distributed constant type filter includes a substrate including a part made of a first dielectric material having a first relative dielectric constant and a different-material part made of a second dielectric material having a second relative dielectric constant different from the first relative dielectric constant. A filter pattern is formed on a top surface and a ground pattern is formed on a bottom surface of the substrate. Part of the filter pattern is formed on the different-material part.

    摘要: An antenna device is disclosed that includes a dielectric substrate having first and second surfaces facing away from each other, an element pattern formed on the first surface of the dielectric substrate, a conductive pattern formed on the first surface of the dielectric substrate so as to extend from the feeding point of the element pattern, and a ground pattern formed on the second surface of the dielectric substrate so as to form a microstrip line in cooperation with the conductive pattern. The ground pattern has a cutout part formed in a portion thereof opposing the feeding point.
