Abstract

This paper presents the design and simulation of a compact capsule antenna operating at the 2.45 GHz ISM band for biomedical applications. A miniaturized meandered microstrip patch antenna is designed using Rogers RT/duroid 5870 substrate to achieve size reduction while maintaining acceptable performance. The antenna is optimized to operate efficiently in a lossy human body environment. A partial ground plane is employed to improve impedance matching and bandwidth. Simulation results demonstrate satisfactory return loss, VSWR, and radiation characteristics suitable for in-body communication.
