A Dipole Antenna with a Dynamic Balun for Wireless Security via Amplitude Based Directional Modulation
Amer Abu Arisheh, Jeffrey A. Nanzer
We present a new approach to secure wireless operations using a simple dipole antenna with a dynamic unbalanced feeding structure. By rapidly switching between two states, a dynami…
Decentralized Localization of Distributed Antenna Array Elements Using an Evolutionary Algorithm
Matthew J. Dula, Naim Shandi, Jeffrey A. Nanzer
Distributed phased arrays have recently garnered interest in applications such as satellite communications and high-resolution remote sensing. High-performance coherent distributed…
Wireless Picosecond Time Synchronization for Distributed Antenna Arrays with Dynamic Connectivity
Naim Shandi, Jason M. Merlo, Jeffrey A. Nanzer
Phase, time, and frequency coordination are crucial for the coherent operation of distributed antenna arrays. This paper demonstrates a high accuracy decentralized time synchroniza…
Multi-Objective Distributed Beamforming Using High-Accuracy Synchronization and Localization
Ahona Bhattacharyya, Jeffrey A. Nanzer
We present a multi-node, multi-objective open-loop microwave distributed beamforming system based on high-accuracy wireless synchronization and localization. Distributed beamformin…
Imageless Contraband Detection Using a Millimeter-Wave Dynamic Antenna Array via Spatial Fourier Domain Sampling
Daniel Chen, Anton Schlegel, Jeffrey A. Nanzer
We demonstrate an imageless method of concealed contraband detection using a real-time 75 GHz rotationally dynamic antenna array. The array measures information in the two-dimensio…
Decentralized Picosecond Synchronization for Distributed Wireless Systems
Naim Shandi, Jason M. Merlo, Jeffrey A. Nanzer
We demonstrate a wireless, decentralized time-alignment method for distributed antenna arrays and distributed wireless networks that achieves picosecond-level synchronization. Dist…
