ABSTRACT
A Triple band Multiple-Input Multiple-Output (MIMO) Rectangular Dielectric Resonator Antenna
(RDRA) is designed using hybrid techniques for Long Term Evolution (LTE) applications was investigated and presented. In recent years, Dielectric Resonator Antenna (DRA) has been rapidly used in RF designs due to small size, light weight, high radiation efficiency, small conductive loss, and ease of excitation and fabrication which is suitable to fulfil current needs in RF design, especially for 5G applications. The Rectangular DRA consists of rectangular dielectric resonator with relative dielectric constant ϵr. The main advantage of Rectangular DRA is that it is characterized by three independent geometric dimensions a, b and d (width x length x height) this offers more design flexibility and low cross polarization levels as compared to other DRA’s.
The proposed MIMO Antenna can transmit and receive data independently by covering LTE Band 8 at 0.9GHz, LTE Band 3 at 1.8GHz and LTE Band 40at 2.3GHz. Hybrid technique is adopted in this design by combining a meander line antenna with an RDRA to realize multiband operation. In this regard it is convinced that proposed MIMO antenna can be a good candidate for LTE applications.
