A system, in a programmable active reflector (AR) device associated with a first radio frequency (RF) device and a second RF device, receives a request and associated metadata from the second RF device via a first antenna array. Based on the received request and associated metadata, one or more antenna control signals are received from the first RF device. The programmable AR device is dynamically selected and controlled by the first RF device based on a set of criteria. A controlled plurality of RF signals is transmitted, via a second antenna array, to the second RF device within a transmission range of the programmable AR device based on the associated metadata. The controlled plurality of RF signals are cancelled at the second RF device based on the associated metadata.

Embodiments of the present dislcosure provide methods, apparatuses, devices and systems related to the implementation of a multi-layer printed circuit board (PCB) radio-frequency antenna featuring, a printed radiating element coupled to an absorbing element embedded in the PCB.
