Abstract: An antenna suitable for portable radios in which two planar conductive boards 1, 2 are disposed in parallel to one another and spaced apart by a distance which is small when compared with received radio wavelengths. A dielectric frame 3 is disposed between the two planar conductive boards to maintain the preselected distance. Arbitrary feeding points are selected along the edges of the two conductive boards and at least one conductor 4 is positioned at an arbitrary selected feeding point to short-circuit the two conductive boards. In some cases a plurality of arbitrary feeding points may be selected along the edges of the two conductive boards and a plurality of conductors positioned at the plurality of arbitrary selected feeding points which short-circuits the conductive boards. The position of the plurality of conductors which short-circuit the conductive boards may be automatically changed to provide the most desirable condition responsive to the direction of the radio waves.

Patent GB-2245523-A (GB)
Title: Composite materials
Inventor: FRY ANDREW ROBERT
IPC: E04C2/34
Filed: 1990-06-19
Abstract: The difficulty of producing composite materials in profiled form is overcome by the provision of a composite material in which a relatively thick core layer (9) comprises a continuous array of open polyhedral frames (10), which frames are bonded at their outermost points to a relatively thin outer layer or layers (7, 8) of a durable, high strength material. The array of frames may be produced by distortion of a suitable expanded metal sheet comprising a two-dimensional network of polygons. The core layer is of relatively high strength and low weight, and can be performed into desired shapes, allowing for ease of production of profiled composite materials. The invention also provides a method of manufacture of such a material, and a structure and a composite panel formed from the material. The material is of use for purposes such as cladding, flooring and panelling, for instance in the building industry.
