Abstract- Antenna is not active device; they are passive that only guides the signal energy in a peculiar direction in connection with isotropic antenna. In this work we have developed a new study concerning low loss microstrip patch antenna by using U-slot loaded patch resonating at multiband frequencies. The goal from this work was to get better VSWR and minimum return loss to design a better multi-band antenna. The parametric study of the designed antenna has been attempted in this research. The main research aspect of the Microstrip Patch is to minimize S-Parameters. To minimize S-Parameters and to match the impedance of the Microstrip Patch antenna several techniques were proposed. The slot on the patch, which increases the fringing fields, remains simple and effective technique. This paper provides an insight in the design of Microstrip antenna and presents a design of multiband antenna after analyzing different U-shaped slots in patch in circular Patch Antenna. HFSS the Finite Element Method based analysis software is used to design the Patch Antenna and to simulate the results.
