Abstract (en)

A device for transmitting electromagnetic energy is provided which comprises a conductive sheet (1), the conductive sheet having: a conductor portion (4); at least one ground plane portion; and at least two rows of slots (3) formed in the conductive sheet separating the conductor portion (4) from each ground plane portion, the slots in each row being periodically spaced from one another and adjacent rows of slots being shifted relative to one another. In use the conductor portion transmits electromagnetic waves. The use of a dielectric material is not required, substantially reducing cost and ease of manufacture. Microstrip-like patch radiators can also be implemented from a dielectric-less microstrip by enlarging the central region of the line. <IMAGE> <IMAGE>
