N2 - A new small antenna consisting of a dipole with left-handed loading is proposed. The antenna is composed of a ladder network periodic structure of unit cells having series capacitors and shunt inductors. Placing capacitors into one side of the network leads to out of phase currents with different amplitudes that allow strong radiation. The numerical analysis show that the antenna has a length of 0.15 wavelengths in free space, input impedance close to 50 Omega and well-behaved radiation patterns, but that losses in the loading components reduce efficiency to 16%. The antenna is compared with other right-handed periodically loading dipoles and shown to less efficient than inductive loading, but much easier to match.
