Abstract

Here 4×4 MIMO configuration array with polarization diversity on a flexible substrate for smartphones. To propose and simulate a single element planar antenna on flexible substrate for 5G communication. Planar antennas, like microstrip antennas and printed circuit board antennas, have both active and passive parts on the same plane. This makes them twodimensional (2D). The idea behind the planar antenna is to make it easier to connect and use with other antennas or communication systems. Because of this, the planar antenna fits the goals of this report because of how it works. The design for the proposed planar antenna was made with the software CST Studio Suite and a specific spectrum of less than 6 GHz. The sub6 GHz spectrum band is a standard frequency for fifth-generation (5G) communication and a fairly new feature and compatibility for smart phones. The results of the simulation showed that the proposed antenna design works at a frequency of 3.5 GHz with an acceptable level of radiation efficiency. MIMO (multiple input, multiple output) technology is also built into the antenna, which improves its performance. This project will make 5G smart phones more useful to their users by making them better at what they can do.
