Abstract
This paper presents a novel reconfigurable MIMO 4×1 microstrip patch antenna loaded with a mixture liquid crystal E7 resonating at 60 GHz for 5G and WiGig applications. The single proposed antenna is a rectangular patch antenna with a total grounded substrate fed with microstrip line. The mixture liquid crystal (E7) is injected in an optimal location underneath the patch and around it. Using the MIMO technology, the gain increases from 7.13 dB for the single antenna to 13.5 dB. Modifying the permittivity of the mixture liquid crystal (E7) allows the adjusting of the resonate frequency. The simulated results of the reflection coefficient show that the resonance frequency tuned from 62.28 to 69.14 GHz, therefore the variation frequency ΔFr= 6.86 GHz characterized with a suitable gain reaches a value of 13.5 dB. The liquid crystal ameliorates performances of the proposed antenna and offers tunability.
