text: Other antennas are directional and must be pointed in a certain way to get the best signal.
text: This assessment assumed (optimistically) that the antenna was a directional antenna array pointing directly at the sun; a rectenna that collects light from the whole sky, like a typical silicon solar cell does, would need the reverse-bias current to be even lower still, by orders of magnitude.
text: Antennas that offer enhanced performance in some directions, at the expense of other directions, are called directional antennas or directional radiators.
text: All antennas are directional to a greater or lesser extent, meaning that they radiate more power in some directions than others.
text: When an antenna is also directional horizontally, gain and ERP will vary with azimuth (compass direction).
text: Direction finding requires an antenna that is directional (more sensitive in certain directions than in others).
text: These antennas are typically very directional and are used for point to point, or to extend the range of a point to multi-point system.
text: It can also address whether the antenna is directional and gather signals from a central location or whether it is multidirectional, seeking signals from towers transmitting from different locations.
