“…However, cavity backed, and crossed-dipole antenna designs may not be potential for RFEH or WPT based portable applications due to their comparatively large structure [151][152][153][154]. In addition, CP antennas with omnidirectional radiation pattern provide additional advantage in RFEH system since these antennas can independently receive radio frequency irrespective of wave's polarization diversity and insensitive to multipath effects.…”

Radio frequency energy harvesting (RFEH) and wireless power transmission (WPT) are two emerging alternative energy technologies that have the potential to offer wireless energy delivery in the future. One of the key components of RFEH or WPT system is the receiving antenna. The receiving antenna's performance has a considerable impact on the power delivery capability of an RFEH or WPT system. This paper provides a well-rounded review of recent advancements of receiving antennas for RFEH and WPT. Antennas discussed in this paper are categorized as low-profile antennas, multi-band antennas, circularly polarized antennas, and array antennas. A number of contemporary antennas from each category are presented, compared, and discussed with particular emphasis on design approach and performance. Current design and fabrication challenges, future development, open research issues of the antennas and visions for RFEH and WPT are also discussed in this review.

“…For example, the AMC ground in Reference15 reduces the antenna pro le to 0.16 λ 0 , but giving two narrow AR bandwidths of 19.3% and 33.8%. In addition, low pro le can also be realized by introducing shorted elements into crossed-dipole antennas [16][17][18][19] . In Reference18, the antenna with a pro le of 0.1 λ 0 achieves an AR bandwidth of 63.4% by adding four shorted parasitic patches on the bottom side of the substrate.…”

A low-profile broadband circularly polarized (CP) crossed-dipole antenna is proposed. In this antenna, the dipole uses a fractal-based structure with multiple similar patches for obtaining broadband CP radiation and impedance matching. The incorporation of the crossed-dipole antenna with four triangular parasitic patches improves both the impedance and axial ratio (AR) bandwidths. Four parasitic inverted-L metal plates are loaded on the ground plane to significantly enhance the AR bandwidth and reduce the antenna profile. The measured results are in agreement with the simulations, which demonstrates that the proposed antenna has a low profile of 0.18 λ0, a -10 dB impedance bandwidth of 91% (2.78~7.42 GHz), a 3 dB AR bandwidth of 81.5% (2.99~7.1 GHz), and a good right hand circular polarization (RHCP) radiation pattern with an average gain of 7.9 dBi over the whole operating band.

“…To suppress the undesired spurious radiations of the unbalanced feeds, external balance‐to‐unbalance transformers (baluns) are generally required, at the cost of sacrificing the available bandwidth and low‐profile property. In addition, crossed‐dipole antennas have been extensively developed as the third kind of wide beamwidth CP antennas 21‐25 . They can simultaneously provide good unidirectional CP radiation pattern and wide AR bandwidth, 21‐25 while most of them have their unbalanced feeds with relatively complex structures.…”

In this article, a balanced low‐profile, unidirectional circularly polarized (CP) stacked loop antenna with wide beamwidth is proposed. The antenna is composed of a pair of stacked nonuniform loops with different radii. The larger loop serves as a principal radiator, and the smaller one acts as an auxiliary one. The feed structure consists of a pair of dipole launchers with vertical transmission line. A bonded coaxial cable is used to simultaneously excite the loops at the center. As experimentally validated, the predicted results are in good agreement with the measured results. Compared to its unbalanced counterparts, the proposed antenna can exhibit impedance bandwidth of 40% (20 log |S11| < −10 dB), 3‐dB axial ratio (AR) bandwidth of 4%, front‐to‐back ratio (FBR) up to 18.5 dB and beamwidths in E‐plane and H‐plane of 118°/90° with low profile of 0.09‐wavelength.
