A single polarized radiator comprising a plurality of planar notch radiating elements arranged on a dielectric substrate. Each notch radiating element comprises: a metallized region on a first side of the dielectric substrate extending across the width of the notch radiating element from a forward edge of the notch radiating element to a rear edge of the notch radiating element, a tuning element in the metallized region adjacent to a feeding point of the notch radiating element, a notch extending from the tuning element to the forward edge of the notch radiating element thereby creating a notch profile, and a plurality of indentations in the metallized region along each side of the notch to extend the length of the notch profile.

Broadband antenna

A single polarized radiator operating within a frequency range, the radiator comprising multiple active dipoles configured to be arranged a predetermined distance from a ground plane. Each active dipole comprising a first active element having first electrical characteristics and a second active element having second electrical characteristics, which first and second active elements are equal in length and provided with a respective feeding point. In each active dipole, first electrical characteristics differs from second electrical characteristics, the length of each active element is selected based on an upper frequency of the frequency range, and the first active element and/or the second active element of each active dipole is/are configured to be capacitively coupled to an active element of an adjacent active dipole.
