What is it about?
Bull's eye antennas are a planar antenna offering similar benefits to horn antennas (narrow beam), without the bulky size. In this paper we show how to mechanically steer the beam on demand.

Why is it important?
Mechanical steering permits a longer communications link to be made than with electronic steering, because there are no phase shifters and power splitters to reduce efficiency.
