Abstract
An attenuation device inclusive of radio frequency (RF) absorber materials to reduce signal power in transmission systems involved in short range communication systems is described. The attenuation device is placed between a radio transmitter and an antenna in a transmission system. The attenuation device may be coated with protective material, and may have small dimensions such that the organization and dimensions of the transmission system are not significantly modified. The attenuation device reduces the power of a signal to be transmitted to a receiver, and has a good return loss indicative of a relatively low mismatch with the antenna.
