Abstract

Design of a coplanar waveguide (CPW)-fed rhombus slot antenna for dual-band operation is proposed. With appropriate rhombic ring feeding structure and rectangular bulge components for impedance matching, the proposed antenna can provide two separate impedance bandwidths of 607 MHz (about 24.7% centered at 2.45 GHz) and 1451 MHz (about 26.3% centered at 5.5 GHz), which satisfies the WLAN operation in the 2.45-GHz band (about 3.4% bandwidth required) and 5.2/5.8-GHz bands (about 13% bandwidth required). Details of the constructed prototypes and experimental results are discussed.
