Abstract

An ultra-wideband monopole antenna for 5G application is disclosed comprising a first quarter wavelength conductor and a second quarter wavelength conductor, for transmitting and/or receiving electromagnetic waves. A flat portion of the first quarter wavelength conductor and a flat portion of the second quarter wavelength conductor are preferably arranged and located perpendicular and intersecting to each other. Two curved wings of the first quarter wavelength conductor and two curved wings of the second quarter wavelength conductor are preferably arranged and located concentrically and having a same center. The first and second quarter wavelength conductors are joined to deliver ultra wideband frequency in the range of 600-960 MHz and 1710-6000 MHz.
