“…The selected criteria for inclusion in this comparison are newly published unidirectional dual-CP/RHCP antennas. Compared with the dual-CP antennas presented in [4][5][6][7][8][9][10], the proposed antenna obtains a much wider effective dual CP bandwidth, without sacrificing the antenna profile performance significantly. Meanwhile, though the RHCP antenna presented in [11] has an advantage on the proposed antenna in effective CP bandwidth, its antenna profile is much higher than that of the proposed antenna.…”

“…Unidirectional dual circularly polarized (CP) antennas have attracted great attention due to their merits of capabilities of reducing polarization mismatch, suppressing multipath interference, realizing unidirectional radiation with higher gain, increasing the channel capacity and link robustness, and enhancing frequency reuse [1][2][3][4][5][6][7][8][9][10][11]. Meanwhile, dual CP substrate integrated waveguide (SIW) cavitybacked antennas have the inherent advantage of mitigating the effect of unexpected electromagnetic interference in the installment environment due to their self-consistent electrical shielding.…”

“…Meanwhile, dual CP substrate integrated waveguide (SIW) cavitybacked antennas have the inherent advantage of mitigating the effect of unexpected electromagnetic interference in the installment environment due to their self-consistent electrical shielding. Though the feature of broad 3 dB axial ratio (AR) bandwidth is becoming increasingly necessary due to the high data rate required by modern services, many newly published unidirectional dual-CP antennas in [4][5][6][7][8][9][10] only support relatively narrow-band applications. In [4], a dual CP SIW antenna consisting of a quarter-mode SIW cavity, two open stubs, and defected ground structures is presented, and it obtains an effective dual CP bandwidth of 11.2% and a much lower profile of 0.03λ 0 .…”

“…In [5], a dual CP metasurface antenna (MSA) with large beamwidth is proposed, which obtains an effective dual CP bandwidth of 12.4%. In [6], a dual CP planar four-port aperture antenna with an effective dual CP bandwidth of 17.2% for 60 GHz applications is introduced. Moreover, a dual CP SIW cavity-backed patch antenna using a two-layer structure is presented in [7], while it has a limited effective dual CP bandwidth of 3.4%.…”

A dual circularly polarized (CP) substrate integrated waveguide (SIW) cavity-backed antenna with the feasibility of obtaining a wider bandwidth and relatively smaller size than other homogeneous referenced antennas is proposed and demonstrated. Fed by a quadrature hybrid coupler, the proposed double-layered stacked antenna, consisting of a perturbed circular SIW cavity and an improved circular patch radiator, is designed, analyzed, and fabricated. Good agreement between simulated and measured results is observed. Simulation and measurement results reveal that the proposed antenna can provide impedance bandwidths of 45.7% (4.74-7.55 GHz) and 46.2% (4.75-7.6 GHz), as well as 3-dB axial ratio (AR) bandwidths of 37.5% (4.74-6.93 GHz) and 37.2% (4.75-6.92 GHz) for RHCP and LHCP, respectively. Meanwhile, within the effective RHCP/LHCP bandwidths, the proposed antenna has gains from 4.8 dBic to 7.6 dBic with an average gain of 6.4 dBic for RHCP, and gains from 4.9 dBic to 7.5 dBic with an average gain of 6.3 dBic for LHCP, respectively. Additionally, the measured effective dual CP bandwidth of 37.2% (4.75-6.92 GHz) not only meets the need for certain or WiMAX (5.5 GHz) band communication application, but also provides the potential to implement multiservice transmission.

“…In the study carried out by Park & Park [62] Left-hand and right-hand circularly polarized (LHCP and RHCP) substrate integrated waveguide (SIW) antenna arrays at the 28-GHz band were proposed for millimeter-wave (mm-wave) applications. A new low-profile dual Cp-planar aperture antenna was proposed by Zhu, Liao, Yang, Li, & Xue [63]. The proposed antenna is characterized by wide bandwidth, high gain, and excellent axial ratio (AR) for 60 GHz applications.…”

The investigation into new sources of energy with the highest efficiency which are derived from existing energy sources is a significant research area and is attracting a great deal of interest. Radio frequency (RF) energy harvesting is a promising alternative for obtaining energy for wireless devices directly from RF energy sources in the environment. An overview of the energy harvesting concept will be discussed in detail in this paper. Energy harvesting is a very promising method for the development of self-powered electronics. Many applications, such as the Internet of Things (IoT), smart environments, the military or agricultural monitoring depend on the use of sensor networks which require a large variety of small and scattered devices. The low-power operation of such distributed devices requires wireless energy to be obtained from their surroundings in order to achieve safe, self-sufficient and maintenance-free systems. The energy harvesting circuit is known to be an interface between piezoelectric and electro-strictive loads. A modern view of circuitry for energy harvesting is based on power conditioning principles that also involve AC-to-DC conversion and voltage regulation. Throughout the field of energy conversion, energy harvesting circuits often impose electric boundaries for devices, which are important for maximizing the energy that is harvested. The power conversion efficiency (PCE) is described as the ratio between the rectifier’s output DC power and the antenna-based RF-input power (before its passage through the corresponding network).
