摘要：This paper illustrates the designing of microstrip patch antenna utilizing defected ground structure. Themajor purpose of designing such kind of antenna is to attain multiband purpose which is vital for requirement oftechnology nowadays. Initiation of such kind of antenna with imperfect structure of ground increases the antennafunctioning. In this case the ground element of the recommended antenna is regarded as defected ground structure(DGS). Moreover the optimization of this kind of antenna is made so as to achieve a return loss of -10db. Furthermorein comparison to simple ground, the recommended design augments the bandwidth and develops the input return lossof the antenna. The antenna design parameters and performances have been studied by means of simulations. Thesubstrate utilized behind designing is of glass with a dielectric constant of 2.2. Moreover the design invariants ofantenna consist of single layer thickness of 2mm as well as operating frequency of 4 GHz. The design was optimized sothat we can get the finest probable effect. To conclude the microstrip antenna without DGS effects in narrow bandwidthwith high return loss. In contrast, microstrip antenna with DGS offers higher operating bandwidth with less return loss.
