Index Terms—HFSS, DGS. I. INTRODUCTION
Microstrip patch antenna is extremely used in many devices, due to its simple and inexpensive nature to manufacture. Patch antenna has a broad range of properties which are very helpful. In recent times, antenna structures are built for dual, triple, and multiband applications [4]. Accordingly, the techniques performed to develop triband are slots and defected ground structure. Based upon the kind of feeding, the suggested antenna gives the final performance. Therefore, contact and non-contact type feedings are accessible for constructing any type of antenna. The noncontact method feeding is hard to fabricate an antenna. Consequently, contact method utilized to excite the antenna. Identifying feed technique for [5,6] a microstrip patch antenna is necessary in designing because it directly shows the impact on bandwidth, return loss and its efficiency. The substrates are used to give mechanical strength to the antenna in microstrip patch antenna. By choosing suitable dielectric medium can decrease the spread of the surface waves. Generally, microstrip patch antenna gives less gain and bandwidth. These parameters can be improved by making changes using slots and DGS technique. The suggested patch antenna with hexagonal slot [1] is designed using FR4 substrate and DGS techniques. It is simulated using HFSS software. II. ANTENNA DESIGN
Microstrip patch antenna consists of three layers; they are ground plane, substrate and radiating patch. The ground plane and radiating patch are etched on either side of the substrate. The substrate used in this proposed antenna design is Fr-4 epoxy with a dielectric constant of 4.4 and the zsssthickness of the substrate is 1.6mm. The strip line feeding technique is used to provide impedance matching, and the proposed antenna is designed using HFSS software. Defected ground structure technique is introduced in this proposed antenna design by cutting the ground L-shape. The dgs technique is used to increase the bandwidth and gain of the patch antenna, and it is used to improve the characteristics of the microstrip antenna radiation.
