Textile Dual Band Antenna Printed on Artificial Heart Bag for WBAN Communications

This article presents a textile dual band antenna printed on an artificial heart (AH) bag for various Wireless Body Area Network (WBAN) communications.The textile dual band antenna operates at two different operating frequencies 2.4 GHz and 5 GHz.The two operating frequencies are reserved for IEEE 802.11b/g/n/ax and IEEE 802.11jWLAN standard.The designed antenna has a frequency bandwidth of (2.3642-2.5375GHz) for the lower frequency of 2.4 GHz and (4.598-5.1683GHz) for the upper frequency of 5 GHz.The dual band antenna is integrated with the proposed AH bag that is made from textile material.The effects of both different materials and dimensions of the proposed AH bag in the characteristics of the proposed antenna are investigated.The effect of the human body on the electrical performance of the proposed antenna integrated with the AH bag is presented.The amount of electromagnetic absorbed energy through the human body is also determined in terms of the specific absorption rate (SAR).The obtained SAR value is less than 0.12 W/Kg.This value meets the IEEE standards.Experimental verification for antenna integrated with AH bag and human body is presented.
