Abstract

A filtering antenna is a type of antenna that not only receives or transmits electromagnetic signals but also filters out unwanted frequencies or interference. It combines the functions of an antenna and a filter, typically a bandpass filter, to only allow specific frequency ranges to pass through while rejecting others. The goal of the current work is to design a Snow flake-Koch fractal microstrip filtering antenna to operate at 2.1GHz and 4.98GHz for 2.1GHz band 5Gn1 LTE Applications and Wi-Fi applications. Better impedance bandwidth is by optimizing the shape of the patch using snow flake fractal up to 2nd iteration. To achieve the filtering characteristics to utilize the proposed design at mentioned applications a Stepped Impedance Resonator (SIR) band pass filter is used with appropriate dimensions. The 10dB return loss bandwidth of the proposed design is 11%, with the maximum gain values of 2.4dB and 2.08dB. It is observed that there is very good agreement between the simulated results and measured results.

Keywords: Triangular patch, Snow flake-Koch fractal, Stepped Impedance Resonator filter, Filtering antenna.
