Massive MIMO technology can increase capacity, data rate, and link reliability significantly without additional bandwidth or transmission power. Most of the previous study on Massive MIMO system are using low frequency (2.6 GHz). This frequency is not suitable for future broadband technology, because IoT devices will use high frequency and possible cell coverage would be smaller.
This work propose Massive MIMO transceiver antenna that can be implemented high frequency (60 GHz). This system provides broadband wireless communication which gives high capacity, high data rate and wide bandwidth. In this works the number of antena is 64 x 64 on one node. Antennas can be set adaptively to capacity. In this case all of the antenna as receiver are functioned to get redudancies and 32 antennas as transmitter adjusted to the required capacity. Configuration of antenna has been set to eliminate the mutual coupling effect. The system utilize full duplex single channel which use the same frequency and time to transmit and receive data. In FDSC, bandwidth can be minimized but there is some bad impact of self interference. The effect of self interference for Massive MIMO transceiver antenna simulated from 10% to 100%.
The proposed system provides the channel capacity = 390 bit/s/Hz or 39x spectral efficiency of SISO system. The simulation result shows that mutual coupling effect = 0. The Massive MIMO have tolerance of 20% self interference effect, however could be decrease 20% channel capacity as well.
