A lighting apparatus includes a metal plate, an insulation layer, a light source, a driver circuit and a wireless circuit. The metal plate includes an antenna area and a base area. The antenna area and the base area are on a same plane. The insulation layer is placed on the metal plate. The insulation layer has a top side and a bottom side. The metal plate is disposed on the bottom side of the insulation layer. The light source includes a LED module. The light source is disposed on the top side of the insulation layer. The driver circuit is electrically connected to the light source via a first conductive path. The wireless circuit is electrically connected to the antenna area of the metal plate via a second conductive path.
