摘要： 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.
