Abstract

The design procedure of the microstrip-fed stepped-impedance (SI) slot antenna has been derived by utilizing the transmission-line and lumped-element circuit topologies. The resonant analysis and modeling of the antenna are also included. This study does not only analyze the SI-slot antenna, but also systematically summarizes its frequency response characteristics, including the resonance condition and spurious response. The design formulas with respect to the impedance ratio of the SI slot antenna are analytically derived. Note that the resonant modes of the SI-slot antenna are predicted without utilizing expensive EM simulation software.
