Design of low power Rectenna for wireless power transfer

Current research trend in the RF wireless power transfer has a shift to new paradigm. Optimization of power transfer for wireless sensor networks has a new facelift due to the evolution of rectifier antenna (rectenna). Wireless powering of sensors with Rectenna has kindled the interest of research society in the present trend. The research developed in the paper bounds within the wireless powering of miniaturized electronics with low power ratings. Wireless powering of sensors has a future potential to be tapped yet. The modelling and optimization that has been carried out have been backed up with simulations and practical experiments which are dealt later in the paper. The efficiency of rectenna can have a significant improvement in working onto the each element of the rectenna circuit as presented in the paper.
