Abstract
RF energy harvesting holds a promising future for generating a small amount of energy to potentially power on a low power device such as wireless sensor network especially in an urban country like Singapore. Due to path loss and restriction on permissible transmission power; the RF power available to the input of the RF energy harvesting system is relative low. In this work, we present a study of ambient RF energy harvesting. We also explore to determine whether another emerging technology wireless power transfer can be integrated with RF energy harvesting. A measurement of the ambient RF power density on GSM 900 and GSM 1800 bands in Nanyang Polytechnic of Singapore is presented. From our conclusion, the harvested energy is not able to directly power the wireless sensor network; however the harvested energy can be stored in a super-capacitor and over some time it can be used to power on the wireless sensor network. So, is RF energy harvesting ever going to become a practical reality? The answer is a cautious yes.

... Recently, in accordance with the characteristics of WSNs packet transmissions, which emit electromagnetic radiation, RF energy harvesting is gaining interest as a potential solution for enabling self-powered low-power platforms. In RF energy harvesting, a variety of research areas has been investigated, including the antenna design for miniaturization and high gain [27], [28], matching circuits for the high efficiency of energy conversion [29], rectifier designs for high sensitiv-ity [30], [31], and the feasibility itself of achieving RF energy harvesting [32], [33], [34], [35], [36], [37], [38]. In particular, the performance of RF energy harvesting was theoretically analyzed by the random arrival model of RF energy source, e.g., a stochastic geometry approach, in [34]. ...

... Radiant energy is harvested from the sun and from radio frequency waves, for both indoor and outdoor systems. In recent years, energy harvesting from radio frequency and sunlight has been explored extensively in an attempt to utilize this source of energy to power wireless sensor networks for environmental monitoring applications (Morais et al. 2008;Bhuvaneswari et al. 2009;Tabbakh et al. 2010;Alippi et al. 2011;Lim et al. 2013;. ...
... In RF energy harvesting, rectifying antennas (or rectennas) are used to capture electromagnetic signals emitted from nearby sources like mobile phones or radio stations, which are then converted to regulated DC power using a rectifier circuit to be utilized by small, low power consumption systems such as sensor devices (Ramesh and Rajan 2014). Some RF sources like radio stations transmit high amounts of RF power (up to megawatts), but due to path loss and fading, their signals reach the harvesting antennas at relatively low levels (Lim et al. 2013), thus making the harvesting process challenging. Nevertheless, RF energy harvesters are promising when implemented in urban and suburban areas due to the large amount of ambient energy sources and the relatively small distance between the RF sources and the receiving antenna (Pinuela et al. 2013). ...

... Among all these methods, radio signal radiated by ambient transmitters became a new source for wireless energy harvesting, and harvesting energy from ambient RF signals can power a wireless sensors network [5]. Besides, recent advance in designing highly efficient rectifying antennas will enable more efficient wireless energy harvesting from RF signals in the near future [6, 7]. More recently, the study of wireless powered communication networks (WPCNs) has received a lot of interest. ...
... Let ℎ í µí± ,í µí±‘ be the source-destination channel coefficients. The channel from the source to the destination is modeled as frequency nonselective fading and additive noise [1, 5, 7]. Therefore, the channel coefficients are assumed to be constant during a complete slot time and may vary from a slot time to another. ...

... Several papers focus on improving antenna performance, e.g. [1] demonstrates a tri-band antenna at 900 MHz, 1900 MHz, and 2.4 GHz, whereas [2] utilizes a large magnetically-coupled coil antenna to increase efficiency. Power management circuits typically focus on low-power conditioning and energy storage such as matching networks, RF-DC converters, and DC-DC boost converters [1]- [7]. ...
... In this system, the RF-DC converter design is important because while the DC-DC boost converter obtains a high efficiency, up to 80%, the RF-DC converter has substantially lower efficiency. Several papers [2]- [4] use Cockroft-Walton RF-DC converters (also called the Villard Doubler) in their RF harvesting systems, while others ([1], [5], and [6]) employ Dickson converters. Yan et al. [7] briefly compares both converters and concludes that there is no significant difference between the two topologies; however, his converters are limited to two stages only. ...
