The far‐field behavior of a chirostrip dipole antenna on chiroferrite substrates is shown using the generalized spectral domain—exponential matrix technique, and such substrates are made from a nonreciprocal chiral medium and ferrite material. Numerical results show that both beam scanning and pattern reshaping can be achieved by adjusting the constitutive parameters of chiroferrite, and the dispersion effects of substrates are considered in detail. © 1994 John Wiley & Sons, Inc.
