Abstract: An ultra wideband antenna using hexagonal shaped ground plane is presented in this work. Presented structure consists of coplanar waveguide (CPW) feed. Hexagonal shaped ground slot results in gradual variation in slot impedance, thereby improving impedance matching. This results in wide impedance bandwidth. A horizontal conducting strip is embedded in the ground plane and is protruded into the ground slot for changing the capacitive reactance of slot impedance. This variation in slot impedance results in single band rejection, extending from 6.7-7.9 GHz. Hence, proposed structure covers the entire ultra wideband range with a single rejection band.
