**4. Conclusion**

In the first part of this chapter, the new coplanar antenna with cutouts on a circular patch demonstrate advantages: larger frequency spectrum, a good VSWR, improved parameter S11. The geometry of the patch was calculated and design with CST microwave studio. The antenna was design for UWB application more likely
