Wearable Rectenna Array for Wireless Power Transmission

Abstract

This paper explains about design of wearable antenna array which is used for receiving the microwave power transmitted at dual frequencies. Direct current power is obtained at the end of rectifying antenna or (Rectenna) composed with filter and Schottky diode. Proposed wearable antenna is designed on jeans textile as a substrate and copper foil tap as conducting material. The antenna array has the dual band resonating frequencies which are 4.65 and 6.85 GHz. Design of rectenna is always a challenging due to the non-linearity characteristics of the diode element; as a result, the filter element is intended with distributed elements. The simulated maximum DC conversion of the circuit is 79% for a power input of 10 dBm with DC voltage 1.6 V at load resistance 550 Ω.
