Analysis of Stacked Antenna in Satellite Application

We propose in this paper a Broadband Stacked Microstrip Patch Antenna structure with a microstrip feeding technique to achieve wide bandwidth and high gain. The proposed stacked antenna executes the frequency range from 4GHz to 10GHz in C band. A parametric analysis is performed to study the inter-element distance effect on antenna performance (directivity, input impedance and radiation efficiency). The results obtained show that in the case of the fully driven element high directivities can be achieved for small distances. The proposed antenna is used for a wide range of applications, such as satellite communication, weather radar systems, applications for Wi-Fi and ISM Band. The C Band is known to perform better on adverse weather conditions than the standard Ku Band for satellite communication. The parameters of the antenna are analysed using the HFSS Tool.
