Directional modulation and artificial noise (AN)-based methods have been widely employed
to achieve physical-layer security (PLS). However, these approaches can only achieve …

A new method of obtaining directional modulation by implementing antenna array dynamics
is proposed. An asymmetric switching feed structure is implemented in a two-element array …

We present a novel, scalable, distributed beamforming receiver array architecture capable of
self-synchronization using an analog phase-locked loop (PLL). Wireless frequency …

We introduce a new technique for secure wireless applications using a single dynamic
antenna. The dynamic antenna supports a constantly and rapidly changing current …

A novel dynamic distributed time-modulated array (DD-TMA) that uses 2-bit phase control for
continuous beam scanning directional modulation (DM) is presented. The element positions …

We present an approach to secure wireless communication based on dynamically changing
the apparent phase center (PC) of a two-element antenna array using spatial amplitude …

We characterize the dynamic complex radiation pattern of a two-element antenna array
employing spatial amplitude modulation. By altering the relative amplitude ratio between the …

We present a dynamic antenna array system for vehicle-to-everything (V2X)
communications applications that is capable of steering a spatially narrow information beam …

Abstract The Moving platform-based Distributed Coherent Aperture Radar (MDCAR) stands
out as a promising technique aimed at enhancing gain, resolution, cost-effectiveness, and …

In this work, we experimentally demonstrate, for the first time, a fully wireless coherent
distributed antenna array (CDA) performing distributed transmit and receive beamforming for …
