A ultra-wideband (UWB) magnetic slot antenna allows for polarization diverse UWB systems when used in conjunction with a UWB dipole, and has the added advantage of reduced cable currents, thus eliminating the need for a balun. These advantages were the motivation behind the development of the complimentary tapered bow tie (COTAB) UWB magnetic slot antenna. The COTAB UWB magnetic slot antenna consists of a propeller shaped slot, excited across the gap. The radiated fields are polarized orthogonally to the orientation of the slot.
