Design, implementation and performance analysis of a high gain UWB slot wearable antenna with human phantom for medical application

Abstract

The paper is aimed at designing a UWB slot antenna with high gain for seamless wireless transmission of parameters of patients for health monitoring. The antenna is designed for UWB with 2 slots; a circular and a diamond slot which helps in wideband communication. The frequency of operation is chosen to be 5GHz with a wide bandwidth from 3 to 6GHz. The antenna is designed using fabrics; jeans, flannel and cotton as its substrate which can be worn by the user. The antenna is simulated in HFSS with human phantom to evaluate the performance. The antenna is compact with dimension of 30∗30∗1mm3. The simulated results show a good impedance matching with return loss below −10dB line and gain of 4.3. The antenna is fabricated and tested with human vicinity and the tested results are best agreed with the simulated results.
