Abstract
Directional antenna apparatus and methods of utilizing the same. In one embodiment, the directional antenna apparatus includes a chip component disposed on a ground plane. The chip component includes a conductive layer disposed upon a ceramic substrate. The conductive layer of the chip component is connected to electronic circuitry via one or more feed structures and one or more ground structures. The chip component and the ground plane are disposed atop a reflector component in a substantially orthogonal orientation. By spacing the ground plane from the reflector component by a set amount, the directional nature of the directional antenna apparatus may be configured.
