Abstract

The emerging technology demands high speed data.5G will provide unbelievable fast broadband speed and capacity to perform every function without drop in connection.The design of microstrip array antenna at 28GHz with EBG structure can meet the demand required by our next generations.The performance and advantages of microstrip patch antennas such as low weight,low profile and low cost made them a perfect choice for 5G application.The main objective of this research is to design the microstrip array antenna with electromagnetic band gap at 28GHz.However in arraying an antenna surface wave current and mutual coupling will naturally occur as one of electromagnetic phenomena between radiating element,which will degrade the gain and antenna performance.The focus of this project is about the Electromagnetic Band Gap (EBG) structure which is used to suppress the side lobe and increase the gain to enhance the antenna performance. The EBG structure is integrated with the microstrip array antenna in CST Simulation Tools.The type of EBG structure and the best arrangement and number of EBG structure integrated with microstrip array antenna were investigated.For the antenna array,the presence of EBG reduces the mutual coupling between two radiating elements.Thus,the final result should be more than 16.5 dB according to the standard ITU-R WP 5D which specify for 5G application.
