UWB Pentagonal Shaped Fractal Patch Antenna for Wireless Capsule Endoscopy

Abstract

The capsule endoscopy device is one of the most important devices that have been invented recently because of its importance in facilitating the process of imaging the digestive system. The process of developing and improving the transmitter in the capsule is one of the most important things to improve images and accelerate the process of imaging. Microstrip antenna will be used because it has several benefits such as small size, ease of manufacture and low cost. In this paper, the microstrip antenna was designed with ultra-wideband technology (UWB) by using fractal geometry. The proposed antenna has a return loss of -25.1 at 5.45 GHz and VSWR of 1.13. Also, the radiation patterns are Omni-directional radiations over the UWB bandwidth.
