Title: Reconfigurable Intelligent Surface Design for Enhanced Beam Steering in Communication Systems
This paper presents a reconfigurable intelligent surface (RIS) design and simulation aimed at enhancing beamforming and beam steering capabilities for 5G and 6G mobile communications. The proposed design introduces a 2- bit unit cell design, having four distinct phase states that can be tuned by a single varactor diode. This configuration has a 5x5 array and provides efficient operation at 23.8 GHz within the 5G New Radio (NR) frequency range 2 (FR2). The proposed RIS design demonstrates unique beam steering capabilities ranging from −60∘ to 60∘ in the azimuth plane which is crucial for extending coverage into the mm-wave coverage. The performance of the RIS is simulated using the CST 3D electromagnetic simulator, focusing on radar cross section (RCS) pattern for optimization. The simulation results reveal effective beam steering capabilities ranging from -10° to -60° and 10° to 60°, with a minimum scan loss of approximately 3 dB. The proposed RIS exhibits the high angular reciprocity that handles the incident waves up to 110∘ at an oblique 60∘ angle.  more » « less

    In this paper, a 1-bit wideband reconfigurable intelligent surface (RIS) design operating at sub-6 band is proposed. The unit cells of the RIS surface are designed based on a three-layer stacked patch structure. Employing a 1-bit PIN diode to reconfigure the phase states, a phase difference of 𝟏𝟖𝟎𝟎 ± 𝟐𝟎𝟎 is observed over the frequency range of 4.81 – 5.77 GHz, corresponding to a 19.2% fractional bandwidth. The reflection magnitude of the unit cell is above –3 dB in the band of interest, and the cross-polarization of the scattered waves is found significantly lower than the single-patch structure. The RIS array with a dimension of 𝟖. 𝟐𝝀 × 𝟓. 𝟏𝝀 , corresponding to a 𝟏𝟔 × 𝟏𝟎 array is structured according to the proposed unit cell with good beam steering capabilities.

    Millimeter-wave (mmWave) communications is a key enabler towards realizing enhanced Mobile Broadband (eMBB) as a key promise of 5G and beyond, due to the abundance of bandwidth available at mmWave bands. An mmWave coverage map consists of blind spots due to shadowing and fading especially in dense urban environments. Beam-forming employing massive MIMO is primarily used to address high attenuation in the mmWave channel. Due to their ability in manipulating the impinging electromagnetic waves in an energy-efficient fashion, Reconfigurable Intelligent Surfaces (RISs) are considered a great match to complement the massive MIMO systems in realizing the beam-forming task and therefore effectively filling in the mmWave coverage gap. In this paper, we propose a novel RIS architecture, namely RIS-UPA where the RIS elements are arranged in a Uniform Planar Array (UPA). We show how RIS-UPA can be used in an RIS-aided MIMO system to fill the coverage gap in mmWave by forming beams of a custom footprint, with optimized main lobe gain, minimum leakage, and fairly sharp edges. Further, we propose a configuration for RIS-UPA that can support multiple two-way communication pairs, simultaneously. We theoretically obtain closed-form low-complexity solutions for our design and validate our theoretical findings by extensive numerical experiments.

    Abstract: This paper includes design and implementation result of an adaptive beam forming antenna for upcoming 5G and Internet of Things (IoT). Switched parasitic array antennas are low cost, small sized and compact circular array antennas that steer beam in a desired direction by variation in switching pattern of parasitic elements. The proposed antenna design has an active center element, which is surrounded by several symmetrically placed parasitic elements. The designed antenna has a gain of 8 dB and is capable of 360 degrees beam steering in steps of 60 degrees each. Simulations are validated with results of the fabricated antenna. Antenna beam is steered by controlling parasitic elements. Future application of Electronically Steerable Parasitic Array Radiator (ESPAR) antennas and switched parasitic array antennas in next generation communication networks and methods for reducing size of the antenna are also highlighted.

    This paper presents modeling and optimization of the steering range of a microstrip planar phased array antenna to steer the unidirectional near-field focused beam towards a certain direction. This antenna can be implemented in headstage-based neural stimulation system and wireless recording system for optogenetic neuromodulation applications. The proposed phased-array antenna consists of sixteen elements that are designed to provide a uniform power transmission over the 27 cm×23 cm×16 cm rat behavioral cage area. The proposed transmitter (TX) antenna implements a near-field-based wireless power transmission system operating at 2.4 GHz frequency. The phased array antenna steers the beam from -30° to 60° in the elevation plane by feeding the individual elements with different phases using four 4-bit phase shifters. A design analysis of the beam-steering approach of the phased array antenna is presented and the corresponding simulation and measurement results are included in this paper.

    This paper presents a flexible 10 × 10 phased-array antenna for efficient and high-gain 3D beam steering applications. The proposed antenna array consists of 25 quadrants of 2 × 2 unit cells, wherein each 2 × 2 unit cell is coaxially fed. The 45° phase shifting lines are incorporated in the feeding paths to facilitate the wide beamsteering range. The dimensions of the proposed phased array antenna (PAA) are 90 × 90 × 0.324 mm 3 . Simulation results show that the proposed phased-array antenna has a resonating frequency at 24 GHz with an operational bandwidth from 23.64 GHz to 24.31 GHz along with a high gain of 29.4 dBi. The array exhibits a maximum beam steering range of 149.8° in the θ axis and 120° in the ϕ axis with a gain variation less than 0.9 dBi. The proposed flexible PAA is suitable for its placement on curved surfaces of autonomous vehicles such as UAVs(Unmanned aerial vehicles).
