Journal of Physics: Conference Series, 2020 Abstract A variant of a broadband antenna is proposed, which can combine up to four antennas with different polarizations and operating frequencies in one design. The antenna is formed in the shape of an annular slot (annular magnetic current) excited at four points through a quarter of the slot perimeter.
