Pinching-Antenna Systems: From Antenna Placement to Antenna Roaming
Kaidi Wang, Daniel K. C. So, Zhiguo Ding
This paper investigates pinching-antenna systems with finite antenna movement speed, under which conventional antenna placement is subject to non-negligible repositioning delay, re…
Age-of-Information Aware Federated Learning with Finite Speed Pinching Antenna
Kaidi Wang, Daniel K C So, Zhiguo Ding
This paper investigates age-of-information (AoI) aware federated learning over wireless networks with finite speed pinching antennas. In contrast to existing studies that assume an…
Energy Efficiency Maximization for Discrete Activation based NOMA-assisted Pinching-Antenna Systems
Yishi Zhang, Aditya Powari, Kaidi Wang +2
Pinching-antenna systems is a promising architecture for flexible wireless communications, but energy efficiency (EE) maximization remains largely unexplored, as limited existing s…
Leaky-Coaxial Pinching-Antenna System with Adjustable Slot Apertures
Kaidi Wang, Daniel K. C. So, Zhiguo Ding +1
As a practical physical implementation of pinching-antenna systems, leaky coaxial cable (LCX) enables distributed radiation in more general wireless environments, particularly for…
Leaky Coaxial Cable based Generalized Pinching-Antenna Systems with Dual-Port Feeding
Kaidi Wang, Zhiguo Ding, Daniel K. C. So
By leveraging the distributed leakage radiation of leaky coaxial cables (LCXs), the concept of pinching antennas can be generalized from the conventional high-frequency waveguide b…
Generalized Pinching-Antenna Systems: A Leaky-Coaxial-Cable Perspective
Kaidi Wang, Zhiguo Ding, Lajos Hanzo
The evolution toward the sixth-generation (6G) wireless networks has flexible reconfigurable antenna architectures capable of adapting their radiation characteristics to the surrou…
