The area of a ultra high frequency (UHF) patch antenna was reduced 80% by embedding high permittivity plugs in the antenna substrate. It is shown that a nonuniform distribution of plugs provides solutions for such problems of the miniaturized antennas as impedance matching and achieving circular polarization of the signal. © 2011 Wiley Periodicals, Inc.
