Abstract
A broadband antenna element capable of operating over greater than an octave band of frequencies is disclosed. The element comprises an open-ended rectangular waveguide section having a loop radiator, formed by shorting an insulated probe to one of the broad walls of the waveguide section, disposed therein. Notches are provided in the narrow walls and flanges are provided on the broad walls of the waveguide section for matching purposes. The insulated probe extends through a hole formed in the rear wall of the waveguide section to connect with a stripline feed network.
