N2 - work proposes a continuously reconfigurable linearly polarized antenna based on a cascaded phase-amplitude-polarization modulation mechanism, enabling continuous fullrange tuning of the linear-polarization (LP) axis from 0° to 180°. The proposed method first converts phase control into amplituderatio tuning through coherent vector synthesis and then realizes polarization manipulation by combining two orthogonal LP components with controllable amplitude ratios. A single control voltage is used throughout the tuning process, simplifying the biasing circuitry while enabling smooth polarization variation. As a result, the antenna radiates LP waves with arbitrary axis angles while maintaining realized gains above 6.7 dBi at 3.2 GHz. A 1×4 reconfigurable array is designed, fabricated, and measured, and the results confirm continuous polarization tuning over the full 0°-180° LP-axis range without significant gain degradation. A wireless image transmission experiment is further conducted, showing that the proposed antenna can effectively compensate for polarization mismatch and improve transmission quality under varying antenna orientations. These features make the proposed design attractive for unmanned aerial vehicle (UAV) terminals and dynamic Internet of Things (IoT) communication systems.
