Design of broadband monopole microstrip antenna using rectangular slot

Abstract

Microstrip antenna suffers from narrow bandwidth. The bandwidth would be enhanced by use of slot. Different sizes and shapes of slots on the patch are of great interest for obtaining optimum results in antenna design. A suitable dimension of the patch along with the position and dimension of the slot is critical in the broadening effect of the antenna. Present study proposed the method of a broadband microstrip patch antenna using slot. The slot used on the patch’s surface affects the radiation characteristics of microstrip patch antenna. This study also presents the choice of size and position of the slot for the broadband antenna. The simulations are conducted using HFSS and ADS, and results of the simulation studies are discussed in this paper.
