A Wideband U-Slotted 1×2 Array Antenna For Energy Harvesting

Abstract

In the manuscript, a wideband 1×2 array antenna is designed and simulated. This array antenna is composed of rectangular patch in which parametric study of U-slot is carried out. It covers wideband frequency range from 1.46 GHz to 6.15 GHz with factional bandwidth of 122.85%. Rogers RT/ Duroid 5880 substrate is used with relative permittivity of 2.20 and dielectric loss tangent of 0.0009. The dimension of this array is 75×105×0.79mm3 with reduced ground plane. Different simulated antenna characteristics such as return loss (< −10 dB), peak gain (13.86 dB) and radiation patterns are obtained to analyze the array performance. This proposed array can be used for energy harvesting applications at GSM, LTE and Wimax bands.
