12 Element Inverted E-Shaped Massive MIMO Antennas for Future 5G Smartphone Applications

In this paper, we intend to employ massive MIMO technology in 5G Smartphone communication. Our aim is to achieve enhanced spectral efficiency and increased system capacity and high gain of the antenna. The proposed model presents the design of a 5G smartphone antenna made of FR4 Epoxy substrate having dimensions of
$161\times 80\ mm^{2}$
. This antenna covers two bands that are 2 - 2.4 GHz and 5.8 - 6.1 GHz. A 12-element Massive multiple input multiple output (MIMO)/diversity antenna system is deemed to function. Twelve identical and highly isolated combinations of inverted E-shaped slot antennas are fed via straight lines in the suggested architecture. In free space, the first frequency band exhibits a returns loss value of −30 dB, second frequency band is −10 dB and an overall antenna efficiency in both bands is greater than 84%. High speed, enhanced capacity, less delay, and quality for transmission and radiation of radio waves in mobile phones are required. Signals from our mobile phones should be launched in a more intelligent manner. An antenna model is shown and explained for future mobile applications.
