Abstract

This paper introduces the design of circularly polarized octafilar helical antenna dedicated for wireless in-body capsule endoscopy applications at 2.4GHz. The use of the circular polarization antenna permits the freedom in capsule orientation during endoscopy process. A multi-layered cylindrical model for the human body tissues is used. The radiation characteristics of the OFHA encapsulated and placed inside the human model have been investigated. The OFHA in capsule module is resonant at 2.4 GHz with an impedance matching wide bandwidth of 125 MHz. The response of the OFHA with and without capsulation is studied. The electrical length of an implantable antenna increases due to high permittivity of the surrounding body tissues. The resonance frequencies for the OFHA with and without capsule is changed to 4.5 GHz and 5.8 GHz, respectively. The radiation characteristics of the OFHA antenna in different cases are analysed and investigated using the finite integral technique.
