In this paper, we propose two types of small antennas for ultra-wideband capsule endoscope systems. One is a conical spiral antenna and the other is a dual spiral antenna. Since capsule endoscope systems work in the human body and transmit internal image data to an external receiver with high resolution, an ultra-wideband small antenna is required. Therefore, to obtain ultra-wideband and small sized characteristics, spiral structures are applied. Moreover, to design an antenna located in the human body, operating frequency of the proposed antenna is determined by considering the electrical properties of body materials. The electrical properties of the human body with dielectric constant of 56 and conductivity of 0.83 are considered. Because of ultra-wideband and small sized characteristics, the proposed antennas are suitable for ultra-wideband capsule endoscope systems.
