There is a lot of demand for the wideband antennas with considerable gain and compactness in size. The modern communication systems need such antennas for reliable data transmission. A novel compact monopole antenna is designed with Koch fractal boundary for wide band applications is presented in this study. The wide band fractal antenna is designed with coplanar wave guide feeding with 50 Ω impedance matching at feed line. The overall size of the antenna is very compact in nature with

The proposed model is constructed initially by taking a basic fractal wide band model operating between 7.8 to 14.5 GHz at higher frequencies with impedance band width of 67%. The proposed antenna covers a wide band between 5-12 GHz with impedance bandwidth of 89%. The proposed antenna characteristics are analyzed with the help of commercial electromagnetic tool HFSS and presented in the study.
