Design of C Shape Modified Sierpinski Carpet Fractal Antenna for wireless applications

Abstract

This paper describes the design of C Shape Modified Sierpinski Carpet Fractal Antenna (MSCFA) at a frequency of 2.4 GHz that support multiband behavior. The proposed antenna operates in S-band (2–4 GHz), X-band (8–12 GHz), L-band (1–2 GHz) and C-band (4–8 GHz) applications. The proposed fractal geometry has been designed by introducing a C Shape slot in the rectangular patch. The Rogers RT/Duroid 5880 material with dielectric constant 2.2 and height 1.6 mm is used for the design of proposed antenna. The proposed antenna is fed by coaxial probe feed. The proposed antenna performance is obtained in terms of Gain, Return Loss (RL), Radiation Pattern, Voltage Standing Wave Ratio (VSWR) and Bandwidth which have acceptable values of return loss less than −10 dB, VSWR less than 2 at each resonant frequencies and Gain more than 3 dB. Return Loss and VSWR of proposed antenna are measured using VNA (Vector Network Analyzer). The measured and simulated results are compared and both are in good agreement with each other.
