Dual Band Octagonal Microstrip Antenna Design Method for Energy Harvesting

Abstract

A practical method to design dual-band octagonal patch antenna IS introduced. The antenna consists of an octagonal patch with a proximity coupling feed designed to radiate at 900 MHz and 1.8 GHz, respectively. The octagonal dual band patch antenna that is designed using the method introduced is then simulated with 3D FEM based electromagnetic simulator. The proposed antenna design can be used to harvest radio frequency (RF) energy from Wi-Fi and widely spread mobile networks. The simulated and analytical results are compared and good agreement is observed.
