Popis: In this paper, a multiple-input multipleoutput (MIMO) antenna with high isolation is designed using defected ground structure (DGS). The proposed antenna is constructed by two sets of four elements (2×2), which are designed at the central frequency of 3.5 GHz for Worldwide Interoperability for Microwave Access (WiMAX) applications. The antenna is fabricated on a FR4 substrate with an overall size of 144 × 99 × 1.6 mm. Thanks to DGS, the designed MIMO antenna achieves a high isolation of 30 dB and a high radiation efficiency of over 90%. Besides, this MIMO antenna attains a 7.5 dBi gain. There is a good agreement between the simulated S-parameters and the measurement results.
