Abstract :Antennas are of great importance in energy harvesting systems. It is possible to collect more energy with RF energy harvesting systems by using multiband antennas. In this study, a microstrip antenna was designed and fabricated for operation at 307 MHz, 1721 MHz, and 5447 MHz frequency bands. The designed multiband antenna with size of 82.05x104.76x1.60 mm3 was optimized for collecting more energy and then, implemented on FR4 substrate. Return loss, voltage standing wave ratio, imaginary and real impedances of the manufactured multiband microstrip antenna were measured by vector network analyzer. The multiband antenna gain was calculated as 2.02 dBi. Furthermore, a good agreement was noted between the measurement and simulation results of the multiband microstrip antenna. As a result, it is determined that the produced multiband microstrip antenna is a useful and suitable antenna for RF energy harvesting circuits.
