SMALL-SIZE QUASI-FRACTAL PATCH ANTENNA USING THE MINKOWSKI CURVE

摘要

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 TM 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.
