Abstract Microstrip antenna suffers from narrow bandwidth. The bandwidth would be enhanced by use of slot. Different sizes and shapes of slots on the patch are of great interest for obtaining optimum results in antenna design. A suitable dimension of the patch along with the position and dimension of the slot is critical in the broadening effect of the antenna. Present study proposed the method of a broadband microstrip patch antenna using slot. The slot used on the patch’s surface affects the radiation characteristics of microstrip patch antenna. This study also presents the choice of size and position of the slot for the broadband antenna. The simulations are conducted using HFSS and ADS, and results of the simulation studies are discussed in this paper. Keywords Microstrip antenna

1 Introduction In last few years, microstrip patch antenna attracted considerable amount of attention of researchers due to demand of its large variety of applications in different fields such as radar, aircraft, missiles, satellite communications, biomedical telemetry, remote sensing, and different other wireless applications. Recently the advancement and spread of the technology in the wireless communication spur the demand for broadband microstrip antenna. The antenna should be compact and low R.G.

volume. Its advantages lies in its low in volume, light weight, easily integration, ease in fabrication and low cost [1]. The conventional microstrip has narrow bandwidth. Its bandwidth is around 5 % and it stances a challenge in the design aspect of the patch to meet the broadband techniques [2]. Serious efforts have been made by the scientists, researchers, and designers to improve the bandwidth of the microstrip antenna [3]. The bandwidth improvement is achieved by loading a different shape and size of slots on the patch or in the ground plane. The impedance bandwidth of the antenna is a vital parameter of antenna. It is the range of frequencies satisfied by the desired antenna characteristics. Over this frequency range the input impedance of antenna is perfectly matched to the characteristic impedance of the feed line. The technique of imparting slot is simple in design and easy in loading and improving bandwidth [4, 5] without increasing the volume of the structures. Therefore, a number of papers have been reported by the researchers for wireless applications on the shape of the slot such
