    • The radiation directivity of radio waves can be controlled more easily over a wider range by using the disclosed dielectric lens. A dielectric lens element having a curved surface is bonded to one of the surfaces of a laminate element in the shape of a flat plate in which a plurality of dielectric layers whose relative dielectric constants are different for adjacent layers are laminated. By controlling the distribution mode of the relative dielectric constants in the laminate element, the radiation directivity for the entire dielectric lens apparatus can be controlled; therefore, the radiation directivity can be controlled more easily over a wider range. A focal point may be positioned within or at the surface of the laminate element, and a signal processing circuit may be formed within and/or at the surface of the laminate element.

    • An antenna device has an antenna part and a filter part combined into a single unit. The antenna part has a radiating electrode formed on a surface of layered dielectric substrates and a grounding electrode formed inside the layered structure. The filter part is formed below the antenna part and includes shield electrodes, capacitor electrodes and coil electrodes. A feed point on the antenna part and an input section of the filter part are electrically connected to each other through a roughhole, and external electrodes are formed on side surfaces of the multi-layered structure of the dielectric substrates, connecting the grounding electrode of the antenna part and the output section of the filter part. A slot electrode having a slot formed therethrough and a strip line extending perpendicularly to the slot may be inserted between the radiating electrode and the grounding electrode of the antenna part.

    • A microstrip antenna (4) has a radiation electrode (2) and a ground electrode (3) which are formed on upper and lower surfaces of a dielectric substrate (1) respectively. A feeding terminal electrode (2c) of the radiation electrode (2) is formed on the lower surface of the dielectric substrate (1), which is provided with the ground electrode (3), and is insulated from the ground electrode (3). A feeding point (2a) of the radiation electrode (2) is connected with the feeding terminal electrode (2c) by a through-hole electrode (2b). The feeding terminal electrode (2c) is formed in the same plane as the ground electrode (3). In another embodiment of the invention, a through-hole electrode (12b) extends from a feeding point (12a) to the plane of the ground electrode (13).
