摘要：In this paper, a simple Inset fed Microstrip patch antenna for ISM band on laminated paper-based substrate is presented for the first time. Paper has emerged as one of the low costs, flexible, eco-friendly organic substrate which is extensively used for wearable body area network (WBAN) applications. But, one of the most important drawbacks of paper-based substrate is that, it is hydrophilic which degrades the performance characteristics of the designed antenna. To mitigate the problem of performance degradation due to ambient humidity of the environment and prolong the lifetime of paper-based electronics, the designed antenna is printed on the paper-based substrate laminated with transparent sheet. The design of the antenna requires the RF characterization of paper with lamination in terms of dielectric constant and loss tangent. Two methods, a cavity perturbation and a transmission line method are utilized for RF characterization of the laminated paper-based substrate. Finally, an inset fed microstrip patch is designed for 2.4 GHz which covers ISM band in free space. Also, its performance characteristics in the vicinity of human body (human arm) is analyzed in terms of SAR which is found to be within the SAR limit provided by FCC guidelines. The simulation and measurement results are in good agreement which confirms the characterization of substrate and the designed antenna is suitable for body area network.
