Title: Novel Sensing Methodology for Initial Alignment Using MmWave Phased Arrays
A novel sensing approach for the single radio frequency (RF) chain millimeter wave systems is proposed. The sensing strategy is inspired from synthetic aperture radar systems, and synthesizes a virtual array manifold vector using a single phased array over temporal measurements. The geometry of the virtual array can be controlled enabling synthesis of both a virtual uniform linear array (ULA) and a virtual sparse linear array starting from a large physical array. Moreover, the proposed sensing can be realized using conventional phased array/analog combiner. Several design parameters of the sensing scheme provide flexibility and are discussed including their impact on initial alignment. The proposed sensing approach allows for a rich set of options for inference. Candidate detection and estimation algorithms are presented and their performance is evaluated.  more » « less

    We propose a novel sensing approach for the beam alignment problem in millimeter wave systems using a single Radio Frequency (RF) chain. Conventionally, beam alignment using a single phased array involves comparing beamformer output power across different spatial regions. This incurs large training overhead due to the need to perform the beam scan operation. The proposed Synthesis of Virtual Array Manifold (SVAM) sensing methodology is inspired from synthetic aperture radar systems and realizes a virtual array geometry over temporal measurements. We demonstrate the benefits of SVAM using Cramer-Rao bound (CRB) analysis over schemes that repeat beam pattern to boost signal-to-noise (SNR) ratio. We also showcase versatile applicability of the proposed SVAM sensing by incorporating it within existing beam alignment procedures that assume perfect knowledge of the small-scale fading coefficient. We further consider the practical scenario wherein we estimate the fading coefficient and propose a novel beam alignment procedure based on efficient computation of an approximate posterior density on dominant path angle. We provide numerical experiments to study the impact of parameters involved in the procedure. The performance of the proposed sensing and beam alignment algorithm is empirically observed to approach the fading coefficient-perfectly known performance, even at low SNR.

    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.

    Abstract Acoustic phased arrays are capable of steering and focusing a beam of sound via selective coordination of the spatial distribution of phase angles between multiple sound emitters. Constrained by the principle of reciprocity, conventional phased arrays exhibit identical transmission and reception patterns which limit the scope of their operation. This work presents a controllable space–time acoustic phased array which breaks time-reversal symmetry, and enables phononic transition in both momentum and energy spaces. By leveraging a dynamic phase modulation, the proposed linear phased array is no longer bound by the acoustic reciprocity, and supports asymmetric transmission and reception patterns that can be tuned independently at multiple channels. A foundational framework is developed to characterize and interpret the emergent nonreciprocal phenomena and is later validated against benchmark numerical experiments. The new phased array selectively alters the directional and frequency content of the incident signal and imparts a frequency conversion between different wave fields, which is further analyzed as a function of the imposed modulation. The space–time acoustic phased array enables unprecedented control over sound waves in a variety of applications ranging from ultrasonic imaging to non-destructive testing and underwater SONAR telecommunication.

    This paper presents a compact phased-array antenna for efficient and high-gain millimeter-wave-based 3D beam steering applications. The proposed antenna array consists of 2 × 2 unit cells and each unit cell is a sub-array comprising of 2 × 2 patch elements connected to microstrip lines that are co-fed by a single coaxial cable. Two 45° phase shifting lines are incorporated in each sub-array to facilitate the wide beamsteering range. The dimensions of the proposed phased array antenna are 24 × 24 × 0.324 mm 3 . Simulation results show that the proposed phased-array antenna has a resonating frequency at 58.4 GHz with an operational bandwidth from 50.1 GHz to 77.5 GHz along with a high gain of 26.8 dBi. The array exhibits a maximum beam steering range of 105° in the elevation plane and 195° in the azimuth plane with a gain variation less than 0.9 dBi.

    This paper presents a magnetic sensor based autotracking method for a phased array based wireless power transfer system to be implemented in neuromodulation applications. This method is proposed to track the position of the receiver(placed on a freely moving animal) and transmit the microwave signal with a focused beam to the target receiver. The coordinate locations of the target are obtained from the magnetic sensor and converted into phase information for the phased array. The system is constructed by a 2.4 GHz near-field 4×4 phased array transmitter antenna with 4-bit phase shifters. The phased array TX antenna steers the beam from -5° to -155° in the θ plane. The magnetic sensor can detect the location of the receiver and the in this steering range. The process of tracking the the target and focusing the beam has been evaluated by simulation.
