Fractal: Impact of feeding techniques on the radiation pattern of modified star triangular fractal

Abstract

In this article, the latest development in the field of fractal antenna engineering are theoretically as well as structurally reviewed and its future scope is discussed. Fractal has unique property that it can make copies of itself at different scales. The concept of fractal antenna is very old but designing for broadband application is quite new. A novel modified star triangular fractal (MSTF) is proposed in this paper. The antenna utilized a coaxial feeding technique and simultaneously possesses multiband, almost uniform radiation, and low profile. The purpose of this paper is to provide the simulated data on modified star-triangular fractal monopole antenna using HFSS based on different feeding techniques. Here we are comparing two feeding techniques and their respective effects on radiation pattern. By the use of microstrip feeding there is ultra-wide band application and in coaxial feeding generates multiband applications.
