Design And Performance Analysis of Rectangular Microstrip Patch Antenna With Half-Hexagonal Fractal Techniques

The compact size of antenna is becoming necessity for advancement in modern technology. In this paper, the design and analysis of rectangular Microstrip patch antenna with half hexagonal fractal geometry has been proposed. The proposed antenna operates at multi-resonant frequencies. The dielectric material Roger RT duroid/5880 has been employed as a substrate material for designing the proposed antenna having thickness 2mm with relative permittivity (ɛr) of 2.2 with loss tangent (δ) 0.0009. The Co-axial feed line has been used to fed the power to the antenna with proper impedance matching of 50Ω so maximum power can transfer. The performance of proposed antenna has been analyzed in terms of return loss (dB), gain (dB), directivity (dBi) and VSWR. The proposed antenna design can be used for S band, C band and X band applications such as weather forecasting, military, satellite communication, wireless communication and radar. The High Frequency Structure Simulator (HFSS) v.13.0 has been used for the analysis and simulation of proposed antenna.
