On the Parametric Analysis of Bio Inspired Printed Monopole Antenna for Wireless Sensor Network in Agriculture

Abstract

Leaves possess garden varieties of shapes and color which attracts the species. But their ability of photosynthesis, they keep the plant alive and strong. This proposed work presents a new design of antenna Biologically inspired from the crops leaf for wireless sensor network operating in agriculture. This work proposes two antenna designs & their comparison. The first design is a most popular rectangular micro strip patch antenna resonates at 2.4 GHz and the second design is a biologically inspires antenna from crops leaves. The results obtained shows that biologically inspired shapes shows good results in terms of size of antenna return loss and bandwidth as compared to traditional antenna shapes. The proposed bio inspired antenna can be embedded in WSN node operating in ISM band. The proposed antenna is a low cost, small size and uses FR4 substrate & resonating at two different frequencies viz. 2.4 GHz & 4.1 GHz with a return loss of −26.18 dB & −16.55 dB respectively. The bandwidth of 158.9 MHz and 145 MHz are obtain at 2.4 GHz & 4.1 GHz respectively which is satisfactory for sensor node operating for monitoring agricultural conditions.
