Abstract :
A compact triple-band coplanar waveguide (CPW)-fed antenna for WLAN/WiMAX applications is proposed. The radiation patch is fed by capacitive coupling of the top transmission line. By only using one metallic strip etched on the bottom of the substrate, tri-band resonances of the antenna are generated. The proposed antenna has a compact size of 30 × 27 mm2, which can provide stable omnidirectional radiation patterns in three bands. The measured - 10 dB impedance bandwidths are 150 MHz (2.39-2.54 GHz), 360 MHz (3.37-3.73 GHz) and 1170 MHz (5.02-6.19 GHz), which is suitable for WLAN/WiMAX applications.
