Abstract :
We present the feasibility and optimization of wireless powering of sensors embedded in concrete that relies on a plane wave propagation model. Transmission loss and propagation loss of RF wave penetrating into concrete at different humidity conditions are calculated for various frequencies, thus an optimum frequency range is identified for the wireless power transmission. The optimized rectenna is also designed for the calculation of battery charging time.
