This article shows a new quasi‐fractal microstrip patch antenna using the Minkowski curve at the radiant and nonradiant margin of this device. The structures analyzed were initially designed using the Ansoft Designer™ software that implements the method of moments. Some antenna prototypes were built and measured. The use of the inset‐fed technique enables a good impedance matching, as can be confirmed by the low return loss obtained (<−25 dB) at the resonance frequencies. Antennas designed using the Minkowski curve presented a reduction of up to 42% when compared with a conventional inset‐fed rectangular patch. © 2010 Wiley Periodicals, Inc.
