A multi-element transmitting antenna composed of white LEDs based on a new white LED radiation model is designed. Effects of parameters used in the design on the distribution of received indoor power are studied, including element layout, LED optical axis polar angle, layer distance, and number of elements. Based on simulation, reasonable design parameters of the transmitting antenna are presented. By controlling
transmitted power of the LED, a design method for transmitting antenna with flat-top distribution of received power is obtained. Simulation and experiments verify the new white LED radiation model.
