Cst software for antenna design6/2/2023 Conducted measurements for reflection coefficient (S 11) and radiation pattern also validate our simulation results. Measurements conducted verify that the designed antenna has wideband characteristics with 50% bandwidth around the center frequency of 2.1GHz. A prototype of the antenna for 1.7GHz to 2.6GHz band is fabricated. The parametric studies used in this paper provide proper trends for initiation and tuning the design. represents different simulation softwares with their features, availability and also focus on designing log-periodic dipole antenna (LPDA) using CST studio. In order to achieve the desired performance of the antenna fine tuning of all sizes of these parameters is required. This paper proposes the necessary conditions for initial approximation of dimensions needed to design this antenna. An in-depth parametric study of these dimensions is presented. These parameters have a considerable effect on the antenna characteristics as well as its performance. A printed Bow-Tie slot antenna with loaded stub is proposed and the effects of changing the dimensions of the slot area, the stub and load sizes are considered in this paper.
