“…A notable innovation is the antenna-in-package concept, which integrates multiple radar antennas on a small chip, also known as single-chip radar. This technology provides sparse resolution for 3D detection and radial velocity measurement using Doppler effect [13] [14]. The advantage of radar over VO is that Doppler radar can directly measure the relative velocity of stationary objects within a single frame, rather than having the relative velocity derived from the changing position of the stationary object in consecutive frames.…”

This paper proposes a novel approach for indoor robot localization that leverages a fusion of information from single-chip infrared (Time-of-Flight) and radar sensors. The aim of our research is the development of a cost-effective and lightweight system that can achieve high-precision robot localization. Unlike traditional localization methods based on LiDARs or cameras, our proposed system uses single-chip infrared and radar sensors to overcome the limitations of high cost and bulky hardware. Specifically, we employ a Doppler radar-based velocity motion model for the estimation of the robot's ego-motion, eliminating the need for additional sensors such as IMU or wheel encoders. Next, we describe a hybrid sensor model for single-chip infrared and radar sensors that provides robust and accurate environmental perception with dynamic outlier removal. Finally, we integrate these components into a Monte Carlo localization framework to generate accurate real-time estimation of the robot's position and orientation. This is the first time a single-chip infrared and radar fusionbased framework has been applied to robot localization, to the best of our knowledge. Through a comprehensive experimental evaluation, we demonstrate the system's high accuracy and efficiency, achieving an average localization error of 9 cm in diverse indoor environments. This remarkable performance, combined with the low-cost and lightweight nature of our proposed solution, positions it as a highly promising alternative for a wide range of applications, including robotics, smart homes, and autonomous vehicles. The significant advancements of this novel approach offer vast potential to revolutionize the field of localization, enabling more precise and cost-effective navigation systems.

“…It is a good candidate widely adopted in latest antenna-in-package solutions to achieve higher system integration and thinner package thickness. [1][2][3][4] However, the pursuit of thinness and miniaturization of the system naturally comes at the expense of antenna gain, impedance bandwidth, aperture size and radiation efficiency.…”

In this article, a low‐profile wideband metasurface‐loaded patch antenna is proposed. The antenna utilizes a compact structure of square ring type metasurface loaded patch to increase the bandwidth of traditional microstrip patch antenna. By introducing a patch‐induced metasurface mode at higher frequency combined with the fundamental patch mode at lower frequency in the band of interest, a dual‐mode operation is revealed with the aid of characteristic mode analysis. Compared with conventional metasurface antenna fed by a long radiating slot, the proposed antenna can achieve a 30% reduction in aperture size with a simpler configuration, clear dual‐mode operation and significant improvement of backward radiation. To validate the concept, a 1 × 4 array prototype of proposed antenna is manufactured under a low profile of 0.04λ0 (λ0 is the free space wavelength at 27.5 GHz). The measured results indicate the antenna array achieves a wide impedance bandwidth of 22.8% with a peak realized gain of 13.1 dBi and a high front‐to‐back ratio over 20 dB.
