Abstract

In this paper, the design of printed bowtie dipole array antenna for rectenna application of radio frequency (RF) energy harvesting is proposed. Rectenna has mainly two main components, i.e. receiver antenna and rectifier circuit. Here, the receiver antenna is intended to operate at the frequency of 1.8GHz in application of Groupe Spe´cial Mobile (GSM) 1800MHz signal response. Bowtie dipole array antenna is chosen as it has simple design and high gain. The antenna is simulated on an FR4 epoxy dielectric substrate with the thickness of 1.6mm. It has been investigated through parametric study to reach the required specification. From the result, it shows that the proposed antenna arranged in 4×1 bowtie dipole array antenna has accomplished the working frequency of 1.82GHz. In addition, some discussion of simulation result will mainly focused in achieving an optimum design of array antenna.
