The described technology uses a dual circularly polarized panel antenna and equal amplitude variable phase control between the two circularly polarized components to achieve a rotatable linear polarization tracking system. An example antenna system includes a plurality of antenna elements that include a plurality of polarization transducers to generate a first signal component and a second signal component from a received wave. A polarization control network applies a phase difference based on an orientation of the linear polarization of the wave with respect to the antenna system between the signal components to generate adjusted signal components. The polarization control network combines the adjusted signal components to form a composite signal that corresponds to the linear polarization of the wave. Linearly polarized transmit and receive signals may be co-polarized or cross-polarized.
