“…Despite the TAA expected low rectenna efficiency at the lower band of frequencies, it's a common case in multiband RF-EH where rectenna efficiency is not high for all the different operating frequency bands. A low efficiency could be obtained due to the lower value of the antenna efficiency at the corresponding frequency and also due to poor impedance matching between the antenna and rectifier at the concerned frequency compared to single-band RF-EH [38], [39]. In a real harvesting case, the ambient RF power is not stable and available all day at one specific frequency according to the conducted RF spectrum study presented in [40].…”

A transparent antenna array based on silver sandwiched indium tin oxide (AgITO) heterostructure thin films is presented. The AgITO is sputtered on both sides of soda-lime glass (SLG) substrate, and the three thin films deposition parameters are optimized to obtain very low ohmic interfacial contact resistance of less than 1 Ω/Sq. AgITO promotes thin film-based transparent microstrip structure of the proposed antenna array as well as the transparent T-junction power divider. Furthermore, AgITO microstrip as well as opaque single element antenna as reference antennas for a transparent array are presented. The proposed array has wide bandwidth promoting radio frequency energy harvesting at Wi-Fi 2.4, LTE 2600, WLAN, WiMAX and the expected 5G mid-bands. Moreover, it could be functionalized for wireless transmission within the previously mentioned bands. The transparent AgITO array has 5 dBi gain value against 2.3 dBi for the transparent AgITO single element antenna at 5.8 GHz. The array was utilized for radiofrequency energy harvesting, obtaining DC output volt=161.4 mV with a conversion efficiency of 32.9% at 5.8 GHz with RF received power of -10 dBm.

“…Therefore, ambient RF energy harvesting can be a proper solution to prevent battery replacement as well as reduce costs. [1][2][3][4][5] Since the power available through rectenna (RF energy harvesting system) is a few microwatts, therefore, they can be used for low power applications such as RFID systems, smart watches, mobile phones, sensors, and telecommunication nodes. 6 To power lightweight wireless devices working at high frequencies, it is beneficial to employ RF to DC energy harvesting systems (rectenna) alongside external batteries.…”

A new multiband circular polarized rectenna is implemented as a radio frequency (RF) power harvesting system tuned for the quad bands of 1.8 GHz (GSM 1800), 2.4/5.8 GHz (WLAN), and 3.6 GHz (WiMAX). An innovative monopole antenna is made for the rectenna; consisting of an octagonal shaped microstrip patch, loaded with an I-shaped rectangular slot and three L-shaped stubs so that the antenna creates circular polarization at the quad bands. The second part of the rectenna is a multi-frequency impedance matching network (IMN) set between the antenna and the rectifier circuit. The IMN includes some parallel shunt stepped impedance stubs (SIS), which provides eight-band matching network and connected to the rectifier, functioning at the frequen-

“…Recently, various single and dual feed CP antenna configurations have been reported for mobile communication, radio frequency identification (RFID), satellite communication, worldwide interoperability for microwave access (Wi-MAX), wireless local area networks (WLAN), and wireless power transmission (WPT) applications [3][4][5]. Most of the antennas reported in the literature generate only one type of polarization, either left-hand circular polarization (LHCP) or right-hand circular polarization (RHCP) [1][2][3][4][5]; however, for polarization diversity systems a dual polarization is needed [6,7]. A single feed patch antenna with two orthogonal slots and two pin diodes was proposed in [8], and by controlling the bias voltage of the pin diodes, the desired LHCP/RHCP pattern can be obtained.…”

The paper presents a new coplanar waveguide (CPW)-fed ultra-wideband (UWB) dual circularly polarized (CP) slot antenna. For realizing UWB, a wide slot is introduced in the ground plane of the proposed antenna. The circular polarization is achieved by introducing a semi-circular stub in the square ground plane. The antenna contains two symmetrical CPW-fed ports at left and right edges to generate dual circular polarization. The evolution steps of the proposed CP antenna are presented, and antenna parameters are optimized to obtain the desired level of isolation, return loss, and axial ratio bandwidth (ARBW). The measured impedance bandwidth (S 11 ≤ −10 dB) of the antenna is 13.5 GHz (2.5-16 GHz); 3-dB ARBW is 75.23% (2.67-5.89 GHz); and isolation greater than 17 dB is obtained in the CP band. The designed dual feed CP antenna has low profile, light weight, compact size, and could be suitable for polarization diversity applications for reducing the effect of multipath fading.
