Textile Horizontal T-Shaped Ultrawide Band Microstrip Patch Antenna for WBAN Applications

In the medical atmosphere wireless body area network technology plays a most common and difficult task for continuous health monitoring. The proposed design’s major goal is to accomplish a low Specific Absorption Rate (SAR) and to get excellent communication in a wireless sensor environment. An antenna is the most common communication equipment in the digital era with its unique designs and excellent findings. The design approach is appropriate to create a new horizontal T-shape slot in a rectangular patch UWB microstrip patch antenna used in medical environments for wearable applications and the designed antenna is simulated using a High-Frequency Structural Simulator (HFSS) utilizing a textile material, denim substrate. The designed antenna resonates at 7.7GHz with an acceptable gain of 4dB. The radiation pattern was measured using an anechoic chamber and the antenna gives a good return loss, better bandwidth, VSWR of 1.05, and the SAR value of the UWB antenna is below 2W. The result shows that the proposed design satisfies the requirements of a textile antenna used as a wearable for monitoring human health continuously in body area networks, technical and military applications.
