Design of Wideband Microstrip-Fed Plannar Monopole Antenna for Multiband Applications.

A novel printed wideband monopole antenna for multiband operations is presented. Good impedance matching in a wide dual-band can be achieved by a simple circular monopole and a rectangular conductor-backed plane with a square hole. The measured 10 dB bandwidth for return loss is from 1.78 to 4.19 GHz about 80% and 5.12 to 6.35 GHz about 21.4% which covering all the 2.4/5.2/5.8 GHz WLAN, 2.5/3.5/5.5 GHz WiMAX, DCS (1710–1880 MHz), PCS (1850–1990 MHz), UMT (1920–2170 MHz), and IMT-2000 (1900–2025 MHz) bands applications. Peak antenna gains have been obtained about 3.39 and 3.96 dBi for the lower and upper bands, respectively. [ABSTRACT FROM AUTHOR]
