Abstract :
The holographic antenna´s efficiency is formulated to determine the holographic antenna dimensions and feed patterns that generate optimal performance. This efficiency comprises three main contributing sources of loss, namely, the spillover, taper, and, termination efficiencies. Antenna measurements using a linear tapered slot antenna as a holographic antenna feed confirm the accuracy of the efficiency derivation.
