Abstract

Configurations of overlapped rectangular patches printed antennas with a slitted ground plane have been investigated. Three overlapped patches are used. The effect of overlapping patches on the impedance bandwidth, input impedance, VSWR, gain and radiation patterns has been studied. Elliptical slit in the ground plane is used to improve the impedance bandwidth of the antenna. Overlapping slots are cut in the radiating surface to reduce the size of the metal material of the antenna. The proposed structure provides 13.3 GHz bandwidth for 10-dB return loss ranging from 3.1 to 16.4 GHz. The simulated radiation patterns are also shown as well. The proposed antenna features UWB behavior with near omnidirectional characteristics and good radiation efficiency.
