Abstract :
A printed ultra-wideband (UWB) antenna operating at the frequency range of 2.9-11.0 GHz is proposed for diversity applications. By adopting two symmetrical P-shaped radiators, the antenna presents wideband impedance matching characteristic. The antenna can achieve good impedance matching and improved isolation by notching a slot at the upper centre portion of the ground plane and inserting a stub in the ground. The simulated and measured results show that the antenna can achieve good isolation. Parametric analysis has been conducted to study the effect of slot width and insertion of stub on the impedance bandwidth and isolation characteristics.
