Abstract
In this paper, design of multiband MIMO antenna by using patch and slot modification is proposed. The MIMO multiband antenna design uses the addition and modification of patch and slot shapes to obtain antenna performance in several frequency bands. In a previous study, the multiband antenna design only used the method of adding patches or slots separately. In this research, we tried to combine the addition of patches and slots together. The antenna design uses the substrate material Rogers RT5880 with a dielectric constant (εr ) 2.2 and height 0.787 mm. The dimensions of the MIMO multiband antenna developed by this study are 42.90 × 14.89 mm. Simulation and measurement results show that this MIMO antenna can work on several millimeter-wave frequency bands, 24 GHz, 28 GHz and 38 GHz. These results prove that the development of design techniques by adding patches and slots to microstrip antennas can produce antennas that work in several frequency bands.
