“…A higher communication rate is also workable for this system instead of a terahertz source with a higher modulation rate. Other coding methods can be further developed for meta‐antenna‐enabled wireless sensing and communication systems in realistic scenarios of ISAC and improve the communication rate, for example, amplitude‐shift keying (ASK), [ 58 ] orthogonal frequency division multiplexing (OFDM), [ 59 ] and quadrature amplitude modulation (QAM). Overall, the use of advanced antenna technologies and modulation techniques has greatly improved the performance of wireless systems, enabling faster and more efficient communication in various applications.…”

Efficient transceivers and antennas at terahertz frequencies are leading the development of 6G terahertz communication systems. The antenna design for high‐resolution terahertz spatial sensing and communication remains challenging, while emergent metallic metasurface antennas can address this issue but often suffer from low efficiency and complex manufacturing. Here, an all‐dielectric integrated meta‐antenna operating in 6G terahertz communication window for high‐efficiency beam focusing in the sub‐wavelength scale is reported. With the antenna surface functionalized by metagrating arrays with asymmetric scattering patterns, the design and optimization methods are demonstrated with a physical size constraint. The highest manipulation and diffraction efficiencies achieve 84.1% and 48.1%. The commercially accessible fabrication method with low cost and easy to implement has been demonstrated for the meta‐antenna by photocuring 3D printing. A filamentous focal spot is measured as 0.86λ with a long depth of focus of 25.3λ. Its application for integrated imaging and communication has been demonstrated. The proposed technical roadmap provides a general pathway for creating high‐efficiency integrated meta‐antennas with great potential in high‐resolution 6G terahertz spatial sensing and communication applications.

In this work, a design of a 3D array antenna based solar panel integration for self-powered applications in modern wireless communication network. Such array configuration is proposed for Multi Input Multi Output (MIMO) applications. The proposed antenna array is structured as a cubical geometry integrated to a solar panel. Such integration is employed to achieve a selfpowered node. The proposed antenna is designed to perform an excellent size reduction at sub-6GHz frequency bands when designed with the aid of the metamaterial (MTM) structures. The antenna performance is enhanced by Moore fractal geometry based on electromagnetic band gap (EBG) defects in the ground plane. The proposed antenna is found to provide a moderate gain at 3.6GHz, 3.9GHz, and 4.9GHz. The antenna array shows low coupling effects, below -20dB, due the array configuration in a cubical shape arrangement. The proposed work is extended to evaluate effectively the bit error rate (BER) and channel capacity (CC), when the proposed antenna system is located in real world communication environments. Therefore, QPSK modulation scheme is considered to suite the applications of 5G systems. The amount of the harvested solar energy is considered the limit to manage the total signal to noise ratio (SNR) in that is applied to the proposed communication scheme. This work is considered for practical aspect issues that is related with amount for the generated power from such integration with solar panel and the total generated SNR. Finally, the comparison between measured and simulated data reveals an excellent agreement between them.

“…These developments have improved various aspects of wireless communications including signal quality, enhanced throughputs, quality of service (QoS), minimizing fading effects, reduced latency, improved coverage, and energy efficiency [3][4]. The reconfiguration mechanism applied to the MIMO antenna permits wireless systems to dynamically adjust and adapt to different communication scenarios, frequencies, or conditions [5]. This flexibility offers several benefits and advantages in terms of frequency agility, spectrum efficiency, interference mitigation, and adaptive beamforming [6].…”

In this paper, a reconfigurable Multiple-Input Multiple-Output (MIMO) antenna array is presented for 5G portable devices. The proposed array consists of four radiating elements and an Electromagnetic Band Gap (EBG) structure. Planar monopole radiating elements are employed in the array with Coplanar Waveguide Ports (CWPs). Each CWP is grounded on one side to a reflecting L-shaped structure that has an effect of improving the antenna's directivity. It is shown that by inductively connecting Minkowski fractal structure of 1 st order to the radiating element, the impedance matching is improved that results in enhancement in the array's bandwidth performance. The EBG structure is used to provide the isolation between antenna elements in the MIMO array. The fractal structure is connected to the L-shaped reflector through four photosensitive light dependent resistor (LDR) switches. The effect of various LDR switching configurations on the performance of the antenna is investigated. The proposed array
