Design and Analysis of the Radiation Characteristics of a Microstrip Antenna Array Resonating at 28 GHz for Satellite Applications

A microstrip antenna array with a resonant frequency of 28 GHz for satellite applications is built, and its radiation characteristics are investigated in this research. The design is a microstrip patch antenna array fed by a corporate network. The Feko Suite was used to examine the radiation properties of the samples. The design was optimised with the help of the optimisation feature in Feko Suite in order to get better radiation properties. The need for satellite applications to operate in the 28 GHz frequency spectrum is also emphasised. An in-depth discussion of the design of a microstrip antenna array as well as the explanation of the results is provided.KeywordsGainMicrostrip arrayReturn lossSeries feedResonant array28 GHz
