Enhanced performances of paper-based Substrate Integrated waveguide (SIW) antenna for Wireless Sensor Network applications

This paper describes a novel structure of substrate integrated waveguide (SIW) antenna. The proposed structure is an SIW square cavity backed circular slot antenna. This paper-based SIW antenna has a linear polarization showing enhanced gain and improved bandwidth comparing to previous paper-based SIW antennas. This antenna operates in Ultra wide band (UWB) frequencies and resonates at 5GHz. The eco-friendly materials used in this work with shielded, compact and easy integration in microwave circuit properties combined with the feasibility to be manufactured with low cost fabrication process leads to develop efficiently, wireless communications systems performances. This antenna is useful in Wireless Sensor Network nodes applications as well as for on body-use.
