Abstract

The antenna is made of a connector and ielectric material in such arrangement that at least a part of transmitted or received energy by the antenna passes through the insulating material. At least two interacting dielectric elements are made and their surfaces are machines in such manner that the conducting material can be placed in selected points. After deposition of the conductive material, the remaining surface areas are coated with an adhesive and joined together, with the conducting material at selected points. Preferably the interacting dielectric parts are semicylindrical and after bonding from a full cylinder. A cylindrical sleeve may be connected to one cylinder end.
