This Letter presents methods for improving the gain and efficiency of a microstrip patch antenna operating at 2.45 GHz implanted in the fat layer of the human body. Simulations using CST Microwave Studio are verified by measurements carried out in an anechoic chamber using a cut of fresh pork meat which has close electromagnetic characteristics to the human body. Using a glass lens and a parasitic ring placed on the skin the implanted antenna gain can be enhanced by almost 8.5 dB.
