Abstract
Controllable directional antenna apparatus and method preferably includes structure and/or steps whereby a Yagi antenna array has a first driven element, a first reflector, and plurality of first directors disposed on a common substrate. The first reflector is bent such that (i) an unbent length thereof is longer than a length of the first driven element, but (ii) a bent length thereof is shorter than the length of the first driven element. A second driven element is also disposed on the common substrate but is angled with respect to the first driven element. A second reflector and a plurality of second directors are also disposed on the common substrate. The second reflector is bent like the first reflector, to reduce the footprint of the array on the substrate. Preferably, the Yagi antenna elements are printed on a printed circuit board.
