5G MMWAVE MIMO ANTENNA ARRAY Introduction  5G uses mmWave frequencies of 24-86 GHz for high data rates  Microstrip antennas suitable due to low-profile, lightweight, easy integration  Antenna arrays can improve gain and bandwidth compared to single elements Single Antenna Design  Rectangular patch on Rogers RT/Duroid 5880 substrate  Inset feed for impedance matching  Resonates at 28 GHz with 3 GHz bandwidth 8-Element MIMO Array  1x8 array with identical patch elements  Spacing of 0.5λ between elements  Achieves 3.94 GHz bandwidth from 26.6-30.54 GHz Results  8-element array provides around 5 dB gain improvement  Radiation patterns show high directivity  14.81 dBi peak gain in array compared to 9.81 dBi in single element Conclusion  Compact 28 GHz MIMO array demonstrated  Array combines elements to enhance gain and bandwidth  High gain and directivity suitable for 5G mmWave systems Key Highlights  Microstrip patch antennas preferable for 5G mmWave due to ease of integration  Antenna arrays essential to achieve required gain and bandwidth  Proposed 8-element design shows significant improvement over single patch  High gain, directivity and bandwidth validate applicability for 5G networks
