Abstract
A luminaire is provided that includes a power circuit that supplies power to a light source, an antenna that at least one of transmits and receives a wireless signal, and a metal housing that contains the antenna and the power circuit. The metal housing has an opening, such that the antenna and the opening are arranged to cause a polarization plane of an electric wave most strongly radiated from the antenna, and a polarization plane of an electric wave most strongly radiated from the opening, to substantially coincide with each other.
