Abstract

In this century’s where the country is preparing for IR 4.0, the revolution of technology has made devices like mobile phone, tablets, laptops, portable devices important in our life. These devices transfer lots of data by using electromagnetic wave to keep up with the technologies. The use of green technology such as RF energy harvesting help in overcoming the problem as the advanced wireless broadcasting and communication system that generated the availability of free energy. However, it also has limitation which is the amount of captured energy of RF source is low. A dual-band operation is adapted on the antenna which can increase gain thus increase the amount of captured RF source. This project proposed on the design of dual-band antenna for energy transfer application with the main objective to design and develop a dual-band antenna that possess dual-band characteristics with improved antenna gain and directivity with the addition of air gap on microstrip antenna design. The development of this project involves the scopes of designing and testing of antenna by using CST software and VNA equipment. In designing process, fundamental parameter of antenna that can improve the performance were analysed and validated. The proposed dual-band antenna can achieve 44.707 dB and 32.163 dB of return loss, and gain of 6.31 dB and 7.82 dB respectively. The antenna has advantage of low cost and high gain for dual band operating frequency.
