“…In [33], this work has a wide scanning coverage and lower side-lobe level, but its bandwidth is narrower, and gain fluctuation is not well. In [34], the tightly coupling array is introduced, which has a wideband but high profile, high mutual coupling as well as low port isolation. The proposed work has a low profile, larger scanning coverage, a lower gain fluctuation, good port isolation and side-lobe level compared with the other works.…”

“…It is an indisputable fact that the dual-polarization wide-angle scanning planar phased array will be a pivotal enabling technology in the 5G communication systems. In recent years, the dual-polarized wide-angle scanning antenna has gotten some achievements based on the above dual-polarized antenna elements [29][30][31][32][33][34][35][36]. The HIS is applied to substitute the ground plane for realizing low profile dual-polarized antenna, where can scan ±50° for each polarization in a wide frequency band [29].…”

“…However, Due to the complexity of the structure, the high cost, and the limited scanning capability, it cannot meet the current relatively high application requirements for the proposed communication systems. Besides, some dual-polarization connected-dipole arrays based on tightly coupled technology are presented in [34]- [36] to improve wide-angle scanning performance. But the tightly coupled array or connected array is not suitable for 5G communication systems (e.g., MIMO) since the interelement mutual coupling is required to be low when each array element works in an active or passive mode independently.…”

A dual-polarized phased array antenna is presented with wide-angle scanning capability in this paper. To improve the mutual coupling in the array, a current cancellation method (CCM) is proposed by changing the current distribution on the excited unit to induce a pair of the canceled currents on the adjacent unit. Meanwhile, this current distribution broadens the beam-width of the unit in the array. Besides, the proposed method can also optimize the array unit size and achieve a small inter-unit distance for wide-angle scanning capability. A lowprofile dual-polarization antenna operating in the bandwidth from 4.4 GHz to 5.0 GHz is designed as a linear array and a planar array to verify the proposed method. Regardless of the linear array or planar array, the mutual coupling in the array is below -19 dB, which is better than that in conventional arrays. Meanwhile, the antenna unit in the array can radiate a wide-beam pattern. Two arrays can scan over ±60° for both polarizations. Within the scanning range, the realized gain reduction is less than 3 dB and the side-lobe level is lower than -7.5 dB. To verify the performance, two array antenna prototypes are fabricated and tested. The experimental results agree well with the simulation.

The research proposed a compact antenna integrated with dual-function solar cells to optimize internet of things (IoT) communication devices and energy harvesting. The use of integrated solar cells with electromagnetic elements as antennas and energy-gathering in a design is a solution for wireless communication sensors and simultaneously electromagnetic and solar energy harvesting. Radiation performance testing of solar cell antennas and optical experiments were carried out to test the ability of solar energy collection. A double feed ring slot circular polarization (CP) antenna coplanar antenna with a configuration has highly sensitive to vertical and horizontal waves. It is to accommodate the impact of circular polarization wave and solar cell distortion on antenna performance. This technology promises green communications, renewable energy, and environmental protection to combine wireless communication and green battery components. The study presents the performance and design results of a double line-feed microstrip antenna circuit connected with CP antenna on the S-band for IoT communication by accommodating electromagnetic energy transmission. The importance of adopting an integrated radio frequency (RF) solar energy harvesting strategy rather than a single source method makes this research very significant in its novelty by optimizing the analysis of multiple signal access in IoT communications.

This paper proposes a programmable solar‐powered radio frequency (RF) transmitter. It employs a novel five‐layer structure that effectively integrates solar cells, active circuits, and broadband antenna. This design can directly emit RF signals without the need for additional power supply, enabling efficient energy conversion and transmission. In addition, a U‐shaped coupling line model is introduced to evaluate the performance of the active circuit. We fabricated a sample and measured it. The results of the measurements indicate that the proposed RF transmitter can achieve self‐powering and programmable output at any frequency within the range of 2.08–4.1 GHz, with an output power of no less than 14 dBm. Moreover, the solar cells are placed on both sides of the circuits and antenna for energy harvesting, achieving 100% sunlight insolation with a 75.5% coverage ratio. This design can be used for self‐powered green wireless system applications.
