RF power harvesting has drawn the interest of research scholars over the past four decades. In this paper a multiband patch antenna has been designed and tested upto 3 GHz. This antenna can be used to harvest energy from GSM/2G/Bluetooth and Wi-Fi frequency thus a single antenna can be used rather than designing different antennas for different frequencies. The reflection coefficient (S11) at 891 MHz (GSM) Band is found to be -24.677 dB and S11 at 2.526 GHz (ISM) Band is -16.83 dB. The VSWR is found to be 1.123 at 891 MHz and 1.336 at 2.526 GHz. As the VSWR is near to unity means that matching is almost perfect at the designed frequency. The maximum power radiated at 891 MHz is 52.07 dBµW/m2 while it is 50.29 dBµW/m2 at 2.526 GHz and efficiency is approximately 51.35%. Thus it is cost effective and easy to utilize for RF power harvesting.References
