Abstract
An approximate LC lumped element equivalent circuit model antenna array for RF harvesting is presented. The array consists of two identical parallels of a resonant circuit that aimed to provide an alternative energy sources for energizing low power devices. The entire structure of spiral inductor array exhibits an aperture size of 14.3 mm × 7.0 mm at a center frequency of 956 MHz. The proposed design is fed by a 50 O microstrip line. A simple of LC lumped element equivalent model and using a magnetic frills model approach is described and to predict the characteristic of spiral antenna array. The results obtained for the resonant circuits through the circuit analysis are compared using the finite integration technique commercial solver and Agilent advanced design system. A good agreement between simulation and measurement results is successfully confirmed.
