Simulation of Design and Analysis Massive MIMO Array Microstrip Rectangular Patch Dualband 3.5 GHz and 26 GHz for 5G Communications

In accordance with the scenario of ITU-R,IMT-2020 or fifth generation (5G) will have 3 scenarios, one of which is Enhanced Mobile Broadband (eMBB). Multi antenna by applying massive MIMO is used on eMBB. Frequency candidates used in the fifth generation (5G) are sub-6 GHz and sub-28 GHz frequencies. This paper focuses on simulating massive MIMO antenna designs that work at 3.5 GHz and 26 GHz frequencies. The antenna is arranged by rectangular patch in the form of an array with 12 patches for the 3.5 GHz frequency and 96 patches for the 26 GHz frequency, so the number of patches on the antenna is 108 patches. The designed antenna will be used as an indoor transmitter antenna. The antenna uses a proximity coupled feed with connectors and dielectric constants 2.2. The designed antenna gets s-parameter result of less than −10.8199 dB, a gain greater than 7.3 dB, and a mutual coupling of less than −32,6201 dB.
