Special Issue Information

Dear Colleagues,

Mechanisms that combine sensing and communication characteristics to provide wireless networking with enhanced performance, operate them with inexpensive and small-sized hardware, and optimize the use of a scarce spectrum are typically referred to as integrated sensing and communication (ISAC) systems. Enabling ISAC requires the research and development of innovative radio frequency (RF) hardware design methodologies. The development of solutions that correspond to ISAC began with a focus on radar many years ago. However, the introduction of multiple-input–multiple-output (MIMO) technology with metasurfaces and antenna arrays at millimeter (mmWave) bands resulted in wireless systems that are well suited for ISAC activities. Contemporary ISAC technologies are evolving rapidly due to the significance of wireless sensing in communication systems and the emergence of new sensing applications made possible by these breakthroughs in technology. The latest developments in ISAC are assisting the scientific and technological community in pursuing applications across diverse domains, notably autonomous driving, military surveillance, internet of things (IoT), unmanned aerial vehicle (UAV) services, radio frequency identification (RFID), and radiocommunication. Comprehensive hypotheses that typically provide additional insights into the best way to solve a variety of communication and sensing challenges, particularly self-interference, polarization mismatch, beamforming, and other RF hardware problems that did not surface during stand-alone layout analysis are introduced by recently released ISAC strategies. Numerous open ISAC constraints remain to be addressed, for instance accomplishing the reliability that is needed for the plethora of sensing services that are anticipated to be provided by prospective radio networks, operating them without interference, and making optimal use of the scarce assets available.

The purpose of this Special Issue of MDPI’s Journal Sensors is to highlight the latest developments in this expanding area of study as well as its present and future problems. Interest-worthy subjects consist of, but are not restricted to the following:

  • Hardware and RF front-end design for ISAC;
  • Antennas and metasurfaces for ISAC;
  • Demonstrators, prototypes, and testbeds to show results;
  • Joint receiver designs;
  • MIMO and massive MIMO for ISAC;
  • mmWave and sub-THz for ISAC;
  • System architectures and integrated design for ISAC;
  • The sensor fusion of ISAC;
  • Use-cases and system analysis for ISAC;
  • Wi-Fi based indoor positioning and target detection/recognition.

This paper introduces an innovative and cost-effective approach for developing a millimeter-wave (mmWave) frequency-reconfigurable dielectric resonator antenna (DRA), which has not been reported before. The antenna integrates two rectangular DRA elements, where each DRA is centrally fed via a slot. A strategically positioned PIN diode is employed to exert control over performance by modulating the ON–OFF states of the diode, thereby simplifying the design process and reducing losses. In the OFF state, the first DRA, RDRA-I, exclusively supports the TE311 resonance mode at 24.3 GHz, offering a 2.66% impedance bandwidth and achieving a maximum broadside gain of 9.2 dBi. Conversely, in the ON state, RDRA-I and RDRA-II concurrently operate in the TE513 resonance mode at 29.3 GHz, providing a 2.7% impedance bandwidth and yielding a high gain of up to 11.8 dBi. Experimental results substantiate that the proposed antenna presents an attractive solution for applications necessitating frequency-reconfigurable and high-performance mmWave antennas in 5G and Beyond 5G (B5G) communication systems.

With the escalating demand for Radio Frequency Identification (RFID) technology and the Internet of Things (IoT), there is a growing need for sustainable and autonomous power solutions to energize low-powered devices. Consequently, there is a critical imperative to mitigate dependency on batteries during passive operation. This paper proposes the conceptual framework of rectenna architecture-based radio frequency energy harvesters’ performance, specifically optimized for low-power device applications. The proposed prototype utilizes the surroundings’ Wi-Fi signals within the 2.4 GHz frequency band. The design integrates a seven-stage Cockroft-Walton rectifier featuring a Schottky diode HSMS286C and MA4E2054B1-1146T, a low-pass filter, and a fractal antenna. Preliminary simulations conducted using Advanced Design System (ADS) reveal that a voltage of 3.53 V can be harvested by employing a 1.57 mm thickness Rogers 5880 printed circuit board (PCB) substrate with an MA4E2054B1-1146T rectifier prototype, given a minimum power input of −10 dBm (0.1 mW). Integrating the fabricated rectifier and fractal antenna successfully yields a 1.5 V DC output from Wi-Fi signals, demonstrable by illuminating a red LED. These findings underscore the viability of deploying a fractal antenna-based radio frequency (RF) harvester for empowering small electronic devices. Full article
