چکیده

In this paper a novel compact ultra-wideband (UWB) monopole antenna is introduced and optimized. Teaching learning based optimization is used in order to obtain the proper UWB bandwidth. The proposed antenna is designed at three stages. In the first stage a basic monopole antenna which operates at 12-14 GHz is designed. In the second stage the ground plane of the antenna is modified and obtains multiple the lower resonance bands. Finally in the last one MATLAB software is linked with High Frequency Structure Simulator (HFSS) software for finding the shape of patch and or parasitic elements adjacent to the patch on substrate. The optimized antenna operates at 2.2-10.2 GHz and 11.2-14.2 GHz for -10 dB impedance bandwidth and has very compact dimensions of 17×17×1.6 mm3. So this antenna is compatible and highly suitable for recent and advanced wireless systems. The antenna gain maximum is 4.1 dBi
