RT/Duroid 5880-based Hook slotted multi frequency low profile patch antenna for WBAN applications

Abstract A triple band RT/Duroid 5880-based hook slotted Antenna for Wireless Body Area Network (WBAN) is investigated in this paper. This antenna can be used for On-body and Off-body communication; it provides wireless link between the wearable devices on the body and away from the body for WBAN users like patients, sports persons, soldiers and firefighters. The fabricated Low profile Patch antenna operates in RF Band, ISM Band and C Band in 1.87 GHz (Upper), 2.45 GHz (Lower) and 5.71 GHz (Upper) respectively. The hook slot designed on the patch antenna is used to improve the performance of antenna in view of WBAN applications. The proposed antenna is fabricated using RT/Duroid 5880 of permittivity 2.25 and tangent delta 0.0004 which is viable to use in wearable and On-body communications. Analysis of the proposed antenna is done by Simulation and fabrication results and their comparison. The low profile antenna performs maximum reflection coefficient value −25.73 dB, directivity 2.86 dBi, 3.39 dBi and 4.59 dBi at 1.8 GHz, 2.45 GHz and 5 GHz respectively, maximum gain 2.85 dB and 1.67 w/Kg SAR levels over 1 g of mass average.
