An antenna, including a broadband vertically polarized monopole radiating element, a reflector having a projection in a first plane generally perpendicular to a vertical axis of the monopole radiating element, a plurality of horizontally polarized radiating elements arranged generally concentrically with respect to the monopole radiating element, each one of the horizontally polarized radiating elements having a projection in a second plane generally perpendicular to the vertical axis, the second plane being offset from the first plane in a direction along the vertical axis and a feed arrangement for feeding the monopole and horizontally polarized radiating elements. |
