Abstract

In this work a cavity-backed, capacitively-fed folded-slot antenna was characterized using Design of Experiments (DOE) techniques to study the influence of the antenna dimensions in the resonant frequency and in the reflection coefficient at resonance. The DOE technique used in the experiment was an un-replicated 2 K full factorial. The experiment was conducted by simulations in the Ansoft's HFSS, and the results obtained were statistically analyzed with the software Minitab. The results reflect with a 99% of reliability only the dimension that affects the responses. These results allow improving the antenna operation and size reduction.
