The impact of feed phase errors on the crosspolarization of offset reflector antennas is studied.The primary feed is assumed to be linearly polarized, with symmetrical E ‐ and H ‐plane patterns independent of ϕ. They are modeled by a cos n θ function, along with an extra term to account for the phase errors. Both linear and quadratic phase variations are studied. A broad range of focal length to diameter ratios, f / D from 0.5 to 1.1, are considered to investigate the crosspolarization properties in the presence of phase errors. It is shown that the reflector crosspolarization increases drastically when there is a linear phase error associated with the primary feed pattern. © 2010 Wiley Periodicals, Inc.
