A low profile dual-polarized unidirectional wideband antenna based on two crossed magneto-electric dipoles is proposed. The antenna consists in folding the radiating element, the height of the radiation element is reduced to 0.11?0 where ?0 is the wavelength at the lowest operation frequency for a standing wave ratio (SWR) <,2 corresponding to a reduction factor of 37%. The antenna has been prototyped using 3D printing technology and evaluated in an anechoic chamber. The measurement results are in excellent agreement with simulations The measured input impedance bandwidth is 54.2% from 1.8 GHz to 2.9 GHz with SWR<,2. © 2016 IEICE.
