Abstract
A feed network device, which is electrically connected to unit radiating elements for circular polarization, may comprise a phase offset compensation circuit configured to correct a phase dispersion error according to a change in frequency so that four quarter arrays obtained by vertically and horizontally dividing a planar array of the unit radiating elements symmetrically are electrically and rotatably sequentially disposed clockwise or counterclockwise.
