Comparative Analysis of Fractal based Nested Triangular Microstrip Antenna: A review

In the last few years there is rapid development in the communication industry. These developments introduced size reduction of the system and are highly efficient. Study of past few years shows that most of the work on MPA is focused on designing compact sized Microstrip Antenna. In this paper we explain a compact multiband fractal antenna based on the nested geometry of microstrip antenna. This antenna is fed by micro strip line. The operation of the microstrip antenna is centre at frequency 2.5 GHz. The paper depicts the design optimization of the nested geometries for multiband characteristics. In this paper three designs are used namely simple nested, truncated nested and simple nested with defected ground structure. Multiband functionality is observed in all the designs presented in this paper. These antenna designs are thoroughly simulated on FR-4 substrate with loss tangent 0.025 and dielectric constant 4.3 and analyzed using Computer Simulation Technology Microwave Studio.
