Abstract
Medical devices implanted in a patient can be activated and powered by an RF signal. Unless the medical device is properly oriented with respect to the transmitting antennas enough signal energy may not be received to power that device. However, optimum orientation can not be assured due to constraints on the implantation position. The present transmitting antenna is flat and omnidirectional thereby eliminating the need to properly orient the implanted medical device.
