Pixel-Based Fluid Antenna System for Device-Free ISAC: Turning Fluid-State Diversity Into Received-Signal-Strength Sensing

Low-cost device-free integrated sensing and communication (ISAC) is constrained by fixed-pattern received-signal-strength (RSSI) measurements with limited spatial contrast. This letter develops a single-RF-chain access point with a 12-bit pixel-based fluid antenna system. Uplink frames support the communication functio...

A Compact Wideband Sub-THz Horn Feed Enabling Metasurface-based ISAC Systems in 6G Networks

A novel wideband sub-terahertz (sub-THz) horn antenna featuring a parasitic dipole integrated with a compact conical horn is presented as the feeding source for a phase-change-material (PCM)-based tunable metasurface. The horn achieves a 43.48 % impedance bandwidth covering from 90–140 GHz, 11–14 dBi gain, axially symm...
