Abstract :
Wide band truncated rectangular micro strip antenna with slot loaded stacked patches and defected ground plane structure is presented in this paper to increase the bandwidth. By inserting slot in the ground plane the bandwidth of the stacked truncated rectangular micro strip antenna is improve by twice. The bandwidth before adding the slot in the ground structure was 29.7% whereas after adding the slot in the ground plane of a stacked truncated rectangular micro strip antenna it increases up to 63.65% ranging from 2.72 to 5.26 GHz. The radiation pattern has acceptable response at both E&H plane. The antenna is design at FR4 glass epoxy substrate fed by a coaxial feeding technique. Detail of the proposed antenna and the simulated results are presented.
