Lockheed Martin Space Systems Company has pioneered advanced antenna solutions over several decades and built a wider range of payload solutions than any other company in the industry. This paper presents a few antenna technologies which has been successfully developed and flown over the years.
In this paper the detection of Orbital Angular Momentum (OAM) modes at a carrier frequency of 10 GHz is evaluated by modelling and by experimentation. A 2-element antenna array together with the phase gradient detection method are used to determine whether a mode 0 or −1 is present, where our results verify that a distinct difference in measured phase profile between the two modes is distinguishable...
