An apparatus and system for incorporating an unshielded antenna into an LED fixture are provided, such that the LED fixture can be individually controlled through RF signals, such as those propagated by a home automation system or other RF-based lighting control systems. An LED fixture is provided that includes an antenna that is coupled to an electronic control board of the LED fixture and extends to a region external to the heat sink of the LED fixture. By extending the antenna in this manner, RF signals can be received and transmitted by the control board of the LED fixture with significantly reduced attenuation. In one embodiment, the antenna is routed from the control board to an optical assembly support frame for the LED fixture. The optical assembly support frame can either provide a structure along which to guide the antenna or can comprise the antenna itself.
