ABSTRACT:
A lossless broadband dipole antenna of length L having three collinear parts including a central part and two external parts. The parts are separated by slits, with a first feeding point for the antenna being located at a first end of one of the external parts nearest the slits, and a second feeding point being located at a second end of the other external part nearest the slits. The two feeding points of the antenna at the slits are arranged at a distance d from each other along the length L of the antenna, d/L being chosen such thatdL=0.37±0.04.
