Popis: Due to the broadband requirements in the field of communication, broadband antennas are becoming popular nowadays. In recent years, both military and commercial applications have been reduced in size, but at the same time the need for broadband antennas is growing. In this context, concepts such as compactness, light weight, small size, low cost and wide bandwidth are the major challenges that wireless communication system designers have to face. In this context, microstrip antennas stand out with their remarkable features such as their simple construction, their small size, their ability to be applied to smooth and sloping surfaces, and their durability when applied to hard surfaces. In this study, a microstrip antenna design with coplanar line feed (CPW-fed) structure operating between 3 GHz and 11 GHz was applied for ultrawide band applications. CST Microwave Studio program was used in the designs. The antenna design is based on the Fr4 base of 1.56mm thickness and 4.4 epsilon. The antenna is 24 mm x 40 mm. Bandwidth, S11, gain and radiation pattern were investigated in the simulations made, the antenna structure showing the best performance was determined by making changes in the parameters and the measurements were completed by the production. As a result of the measurements made, the gain of the antenna model between 3 GHz and 11 GHz is S11
