Abstract :
A circularly polarized microstrip antenna with poly fractal boundary is proposed. The sides of a square patch are replaced with Minkowski and Koch fractal curves along x and y axes respectively for generating asymmetry in the structure to get circular polarization in the radiation. The corresponding poly structure is implemented over a Reactive Impedance Surface (RIS) for broadband operation. Simulations for poly fractal antenna are carried out with square and fractal RIS elements.
