The proposed passive device autonomously adjusts the phase shift of a two-element array proportional to the panel rotation. Consequently, the main beam is steered to compensate for panel rotation and maintain a radio link. The proposed device operates for a rotation of ±45° with an amplitude variation of <0.4 dB at 2.51 GHz.en621journal article
