Multi-band fractaled triangular microstrip antenna for wireless applications

Abstract

The proposed microstrip antenna is based on fractal techniques and designed for wireless applications. The radiating element is an A-shaped triangle on which fractal concept is applied. Fractal concept is applied on the proposed A-Shaped Fractal Microstrip Antenna (ASFM-Antenna), similar to English alphabet letter A. Further the analysis and verification of result is achieved by testing the fabricated antenna and also comparison of simulated and experimental results. Von Koch’s snowflake concept is used in which a single line is divided into four new lines, and it is done at each side of the triangle. This step is repeated. In this paper, a two-iteration Koch generator is used, thus the proposed antenna is designed. Simulations are carried out using commercially available HFSS (High Frequency Structure Simulator) based on finite element method. The antenna is simulated and fabricated, and results are recorded. It is found that simulated and experimental results are in close agreement with each other. The antenna resonates at 11.44 GHz, 13.178 GHz, 15.482 GHz, 19.902 GHz and 23.529 GHz. Hence, X-band [8.2-12.4GHz], Ku-band [12.4-18 GHz] and K-band [18-26.5GHz] are the frequencies of operating bands under consideration.
