A Novel Microwave Imaging using Flexible Triangular Fractal Monopole and Antipodal Vivaldi Antennas

Designing an antenna is a significant challenge with as small-size and high performance architecture. The novelty relies in the changes that would have been adopted on the fundamental shape of the antenna. The Fractal antenna is designed based on the composite structure formed by the repetition of fundamental shape without altering the self-analogues and space occupying feature. In this design, the ISM band monopole antenna structure is planted on a Sierpinski Gasket with the help of iterative triangular function systems. In this paper, convergence criterion of a moment of a Vivaldi antenna and mesh convergence of a simple dipole antenna was investigated with a new novel design-"Antipodal Vivaldi Antenna" which can be used with various biomedical applications.
