“…In their work, N is the number of rectenna in one row/column of the designed rectenna array; although, the criteria for its selection is not specified. In work [30] authors have implemented mathematical model to represent vast rectenna array as the single equivalent element of the rectenna. The developed model by researcher is useful for RF harvesting system performance characterization, although work does not discuss about rectenna panel design parameters.…”

Now-a-days, far-field wireless power transfer/energy harvesting is underutilized due to the unavailability of proper methodology to design efficient system for maximum radio frequency (RF) power utilization. For efficient utilization of far-field RF energy an array/grid of rectenna, i.e. rectenna panel is required to generate the power from wireless signal. To minimize the engineering design phase period (design trials), this paper mathematically derives and summarizes the approach required for optimum rectenna panel design based on power available in the environment, RF transmit source capability, receiver power requirement and the design cost. For maximum power interception through a rectenna panel, its design parameters such as -panel size, number of rectenna, rectenna arrangement pattern, and rectenna spacing has been optimized in our work. Based on the optimization required, we have proposed the compact grid pattern with heterogeneous rectenna spacing. It has been proved theoretically in this paper that if a hexagonal shape panel is designed by placement of rectenna at vertices of equilateral triangle (with side length governed by antenna aperture) then, it is capable of intercepting maximum RF energy available at its location with the least number of rectenna.

This paper focuses on designing a circuit that rectifies background radiation and one that is self-biasing. This circuit set-up is called a rectenna which is a special type of antenna that is used to convert radio-frequency energy into direct current electricity. A simple model of a rectenna element consists of a monopole antenna with an radio frequency(RF) diode bridge connected in series with the antenna. The bridge rectifies the ac current induced in the antenna by the electromagnetic radiation to produce dc power which is used to bias a Bipolar Junction transistor(BJT). RF sensitive/high switching diodes are usually used because they have the lowest voltage drop and highest speed and therefore have the lowest power losses due to conduction and switching. The BJT transistor has a feedback biasing and essentially amplifies the ac signal from the antenna. The amplified signal is fed into an RF diode for dc conversion. There are two stages of amplification in order to achieve a big voltage magnitude at the output that can be used to charge a device with low power ratings. Thus the idea of a cell-less power source is achieved in such implementation.

“…However, these retennas are generally designed at a single frequency band, and high power density is required. To harvest more ambient RF energy from multiple frequency bands, a reasonable solution is to use a multiband or broadband antenna array which is able to operate at low power density [6][7][8][9][10][11][12]. However, the multiband or broadband antenna array usually has a large dimension, and the complex structure of the array may result in coupling between the antenna elements which reduces the efficiency of the elements.…”

Abstract-With the increase of low power devices, the design of a compact and efficient rectenna is essential for supplying energy to the devices. This paper presents a compact rectenna for high efficient WiFi energy harvesting. A novel fractal geometry is introduced in the design of antenna for miniaturization, and the ability to harvest WiFi energy is enhanced due to its characteristics of self-similarity and space filling. Besides, a single stub matching network is designed to achieve high conversion efficiency with a relatively low input power ranging from −20 dBm to 0 dBm. Simulation and experiments have been carried out. The results show that the proposed antenna features a good characteristic of reflection coefficient and realized gain at WiFi band. The highest RF to DC conversion efficiency of the rectenna is up to 52% at 2.45 GHz with the input power of 0 dBm. This study demonstrates that the proposed rectenna can be applied to a range of low power electronic applications.
