Abstract
A telecommunication system antenna including: a non-resonating three-wire type folded element which generates an unbalanced mode current and has a matching function; a sleeve element which consists of a conductive sleeve with its one end near the non-resonating three-wire type folded element and a conductive disk in a flange shape around the circumference of the other end of the conductive sleeve, so that the sleeve element radiates electromagnetic waves based on the unbalanced mode current generated by the non-resonating three-wire type folded element; and a coaxial line with its tip end inserted into the conductive sleeve of the sleeve element from the other end of the conductive sleeve so that the coaxial line is electrically connected to the conductive sleeve and to the non-resonating three-wire type folded element.
