    Abstract: An antenna comprises a plate conductor 1 with a slit 2. The said plate conductor 1 is electrically connected to a spaced and parallel back plate conductor 4. A conductor line 6 is arranged to span the slit 2 and is connected to the plate conductor 1 on a conductive route from the slit 2 towards the electrical connection 3 extending between the plate conductor 1 and the back conductor 4. The plate conductor 1 may be rectangular with the slit 2 formed in an orthogonal manner to the long edge of the plate. The conductor line 6 may be a conductive member of a coaxial feed 5, a microstrip transmission line or a twisted pair. The other conductive feed-line member 7 may be connected to the plate conductor 1 on the side of the slit 2 which is opposite to that of the first mentioned conductor line 6 by a line or spot electrical connection. A microstrip transmission feed-line may be used which includes a microstrip line with an enlarged end, of various shapes. The U-shaped conductive member of the antenna may be formed by folding a metal plate or an integrated assembly of conductive plates and vias. The antenna may include insulating material such a circuit board. The insulating material may be a foldable cloth, sponge, film or flexible printed circuit board. The simple antenna construction may provide a small, thin and cheap foldable broadband antenna which may be fastened to clothing using a releasable fastening.

    Abstract: A lens antenna is disclosed which comprises a conical horn and a lens attached to an aperture of the horn. The lens has a first planar surface at a first side which faces free space and a hyperboloid of revolution at a second side opposite the first side and is made of a dielectric material with relative permittivity ranging from 2 to 4. The lens is provided with a cylindrical portion which has a second planar surface parallel to the first planar surface and displaced from the first planar surface by a predetermined distance. The cylindrical portion being concentric with the lens.

    Abstract: In a radiation element comprising helical element (1), diode (2), and helical element (3), since helical element (1) is insulated from helical element (3) for a high-frequency signal when diode (2) is off, only helical element (1) operates as a radiation element. In the radiation element comprising helical element (1), diode (2), and helical element (3), since there is conductivity between helical elements (1) and (3) for a high-frequency when diode (2) is on, helical elements (1) and (3) operate as connected.

    Abstract: A helical antenna comprising a cylindrical dielectric member 1, four spiral conductors 2a to 2d which are wound around the outer wall of the cylindrical dielectric member 1, four spiral conductors 3a to 3d which are attached to the inner wall of the cylindrical dielectric member 1, and power supply circuits 4, 5 for supplying high-frequency power to the spiral conductors 2a to 2d and the spiral conductors 3a to 3d respectively. That is, the spiral conductors serving as radiation elements are disposed at the outside and inside of the cylindrical dielectric member, and the outer and inner conductors are operated as independent helical antennas. These spiral conductors are connected to the power supply circuits for supplying the high-frequency power having desired amplitude and phase.
