Abstract

Due to various benefits, Microstrip patch antennas are utilized in different applications extensively. Because of the attractive features of ease of fabrication, robustness, light weight, and low profile, microstrip patch antennas have been investigated. However, the significant disadvantage is the narrow bandwidth that is where stacking of antennas is proposed. The stacked antenna is designed to form an array which is used for enhancing bandwidth. The stacked antenna offers many advantages like miniaturization, frequency independent, wideband and multiband capabilities, low volume, smaller dimension and many more. With a rectangular slot, a rectangular microstrip patch antenna is designed in this project and it is replicated based on HFSS tool. A 1*1, 1*2 and 1*3 stacked antenna designs are proposed using line and coaxial feeding techniques. The proposed antennas are intended at a frequency of 2.8 GHz with a substrate of FR-4 EPOXY that has a dielectric constant of 4.4.it has features like enhanced bandwidth which is one of the concerns for this project. For proposed 1*1, 1*2 and 1*3 antennas the feeding techniques used are microstrip line feeding and coaxial feeding. For feeding, inverted T shaped microstrip line feeding was used. Here full ground plane is considered for ground structure. The antennas resonating ate 2.8 GHz frequency meets the desired requirements of VSWR and return loss. The stacked antenna array with a thin slot achieves a better result than single antenna. The HFSS (High Frequency Structured Simulator) tool is utilized to evaluate the performance characteristics of the designed antenna such as Return loss, VSWR, Directivity, Gain and radiation pattern
