Abstract

In this paper an efficient penta-band microstrip-fed slot antenna with a compact size of 38×19 mm² is presented for wireless applications. Each band can be controlled in a wide range by variation of only one dimension parameter whereas other bands remain unchanged. Variation ranges are from 2.3 to 2.62 GHz for f₁, 4.25 to 4.76 GHz for f₂, 5.7 to 6.35 GHz for f₃, 6.72 to 7.35 GHz for f₄ and 7.55 to 8.35 GHz for f₅. Also a measured bandwidth of 130 MHz (%5.3 at 2.47 GHz) is achieved for the first resonance.
