Traditional radio-based systems often suffer severe attenuation underground, as soil and rock absorb or scatter electromagnetic waves. By contrast, magnetic induction uses low-frequency magnetic ...
K-LOVE Radio’s recent upgrades with GatesAir in Montana and Utah show how modern transmitter design can deliver operational, ...
Abstract: Contemporary communications systems use large arrays in order to exploit the spatial domain requiring multiple radio-frequency (RF) chains leading to prohibitive cost and power consumption.
Abstract: This work proposes a reconfigurable antenna array with integrated radiation and scattering modulation. By controlling the PIN diode states on a ladder-shaped patch element, a 180° phase ...
