This paper presents microstrip patch antenna with microstrip feed, operating in medical implant communications service (MICS) band (402 – 405MHz). The proposed antenna has a simple rectangular structure is made up of FR4 substrate having dielectric constant 4.4 and conductivity 4.9 x 107. The antenna structure is simulated using IE3D software and significant antenna designed parameters are also studied. Simulatation result shows that the proposed structure covers MICS band with center frequency at 403MHz. Because of its rectangular structure the proposed antenna is very simple to design, fabricate and analyze when compared to the existing antennas (spiral, fractal etc) which require heavy numerical computations. The dimension of antenna is further miniaturized by using substrate of high dielectric constant like silver.
