Design of a Dual Band 2.45 GHz and 5.2 GHz Microstrip MIMO Antenna with T-Geometry based on AMC Reflector

Multiple input-multiple output (MIMO) is one of the important applications of WLAN wireless communication technology. In wireless communication systems, especially with the developing services, an increase in data speed and access quality is required in indoor WLAN systems for multi-media data transmission. In new-generation wireless communication systems, high transmission performance and high data rates can be achieved with MIMO systems that use multiple antennas in the sender and receiver. In the MIMO system, parallel data transmission can be made over multiple antennas at the same time and frequency by using the spatial domain. In this study, a MIMO dual-band microstrip antenna with artificial magnetic conductive surface T geometry operating at 2.45 GHz and 5.2 GHz was designed. CST simulation program was used in the designs. To increase the efficiency of antenna parameters; an artificial magnetic conductor design (AMC) was made and used as a reflector for the antenna. The designed dual-band MIMO microstrip antennas; parameters such as reflection coefficient, radiation diagrams, and gain were examined.
