Abstract

Background/Objectives: In multimedia data communication environment a trade-off shall be opted between power, spectrum needs and wireless channel capacity in Global System for Mobile, Long Term Evaluation, and Wireless Local Area Networks applications. Multi-Input Multi-Output antenna elements display a high degree of similarity and it leads to efficacy reduction in multi user milieu. Methods: This paper investigates and presents a condensed 2-port coax fed multiband MIMO antenna for 4G applications. The proposed MIMO antenna possesses dimensions of 45mm×50mm×0.4mm3 and comprises two layers, a rectangular patch, a pair of small-N shaped strips, two G-shaped monopole structures and L-shaped slots. An array of three resonant frequencies is opted for exciting the proposed design with the values of 1.8GHz, 2.5GHz and 5GHz. The methodology exhibits an adaptable frequency selecting with the ability to neutralize the impact of the other frequency. Findings: The implemented design accomplishes a high efficiency rates for LTE-Advanced, WiMAX and Wi-Fi applications 71.80%, 72.28% and 85.74%. Applications/Improvements: Fabrication with a suitable FR4 substrate material is used in the design of the coax fed multiband MIMO antenna. For future enhancements, the radiation pattern and reflection coefficient of an antenna shall be assessed.
