“…Steering and changing the direction of a single main beam of an array is referred to as beam scanning. The beam scanning method is potentially a promising technique to direct microwave power after finding the location of receiving appliance in WPT scheme [216][217][218]. The pivotal component for beamforming and beam steering is phased array antenna [219].…”

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.

“…By adopting the Yagi-Uda concept [16], [17], the proposed antenna achieves stable S 11 multi-mode beam steering with a high tilted beam angle by introducing non-linear interparasitic element spacing. This antenna has attributed a lower design complexity compared to the prior antennas [10], [11], [12], [13], [14], [15], [18]. Besides that, the four PIN diode switches are located at the parasitic patches layer.…”

A low-profile and broad steerable patch array antenna is presented. The improvement of the multi-directional functions from the broadside is very limited for the patch array antenna. In this work, the number of directional beams is enhanced by 40% using a novel approach, inter-parasitic element expansion technique and adopted only four PIN diode switches. Results in simulation and measurement have verified that the patch parasitic array antenna is capable -of generating seven beam patterns directed towards -52 • , -30 • , -10 • , 0 • , +10 • , +30 • , and +52 • at the xz-plane. Applying the inter-parasitic element spacing's optimization and minimizing the switching circuitry using four RF PIN diodes on the parasitic elements have contributed to the gain achievement of more than 7 dBi.INDEX TERMS Antenna and propagation, multi-directional antenna, reconfigurable antenna.
