Printed monopole antenna for wireless sensor network

Abstract

Wireless sensor network (WSN) are networks that consist of spatially distribute device using sensors to monitor physiological conditions, agricultural environment and disaster rescue. One of the important components in WSN communication is antenna. However, WSN as an individual node faced a lot of constraints in terms of limited processing space, storage capacity and communication bandwidth. This is because; it has to be low in energy source. Thus compactness and small design are crucial for WSN antenna. The focus of this research is to design WSN antenna with reduced size. Based on modification from several research papers, three monopole antenna configurations are proposed C-shaped monopole antenna, loop monopole antenna and S-shaped monopole antenna. Parametric investigation is then carried out to achieve size reduction as well as desired frequency of operation of 2.45 GHz. This proposed design is then simulated and fabricated to obtain the properties of the antenna. C-shaped monopole and loop monopole antenna successfully achieved the desired frequency and size miniaturization and can be used for WSN application.
