Abstract

In this paper, a new conformal monopole antenna is presented. The proposed antenna is suitable for using in wireless capsule endoscopy (WCE) as transmitter antenna because of its special structure. The WCE antenna should have particular features, because it will be radiate in human body environment. The WCE antennas specific requirements are: proper size, location, gain, radiation pattern and bandwidth in standard frequency band. The proposed antenna’s basic design is done according to the monopole antenna. Therefore, the antenna radiation pattern is omnidirectional. In order to achieve proper bandwidth the Babinet’s principle is applied to the monopole antenna. Also, the antenna is placed in the capsule’s dome. Finally, the antenna simulations are done with two High Frequency Electromagnetic Field Simulation and Computer Simulation Technology Microwave Studio software. The design results show that the antenna gain is − 30 dB and 89% bandwidth in Industrial, Scientific and Medical band. Therefore the proposed antenna will be an appropriate candidate for using in WCEs.
