“…A MIMO mm-Wave antenna operating at 24 GHz is proposed in [18], which is ideal for wearable applications. In [19], a dual-polarized broadband horn antenna for mm-Wave 5G application and in [20], a MIMO DRA with enhanced isolation with the help of metal strips are proposed. In all the proposed work in the literature, the isolation is improved with the help of external decoupling structures.…”

A rectangular Dielectric Resonator Antenna (DRA) four element Multiple in Multiple Out (MIMO) is proposed for 5G application, and each element is supplied with slot-coupled microstrip feed. The entire construction has a dimension of 20 mm × 40 mm. Four Dielectric Resonators are mounted exactly above the slot. In order to improve the isolation, metamaterial is printed on top of the dielectric resonators, which move away the solidest coupling fields. As the metamaterial structure interacts with electromagnetic fields, field distributions are disturbed which results in reduction of coupled fields. Since the metamaterials are printed on top of the dielectric resonator, the proposed antenna structure has the simplest and compact design. The proposed structure is operating with an impedance bandwidth of 2.23 GHz with operating range from 26.71 GHz to 28.91 GHz, which covers the 28 GHz (27.5 GHz-28.35 GHz) band allotted by Federal Communications Commission (FCC) for 5G application. With all four-port excitation, the proposed structure shows a broadside radiation pattern with gain above 7 dBi in the entire operating bands. The Envelope Correlation Coefficient (ECC) for operating bands is within the target value. They are designed and fabricated to validate the proposed antenna. The simulated and measured values are nearly equal, which means that the proposed MIMO DRA is the right choice for mm-Wave 5G implementation.

“…H ORNS are one of the most widely used microwave antennas due to their simple structure, high gain, and versatile design. Horns are used as antennas for 5G and millimeter-wave applications [1]- [3], antennas for electronic warfare (EW) [4], [5], and feeds for lenses [6], [7]. To attain high gain with a conventional horn, wide aperture size and low flaring rate are required making a relatively long focal distance from the phase center to the aperture.…”

In this paper, we investigate a shortened horn antenna with high gain that is enabled by a 3Dprinted gradient index (GRIN) lens composed of high permittivity zirconia (ZrO 2 ). The baseline H-plane sectoral horn antenna is designed with length that is 1/3 of the optimal horn antenna and exhibits a low gain due to the high flaring rate of the horn. Increased gain is achieved by adding a flat GRIN lens at the horn aperture. High permittivity ZrO 2 (ε r = 23) enables lens miniaturization; however, when interfaced with air, reflections at the air interface increase the impedance mismatch. Two different methods for mitigating the reflections are studied. One is a simple λ/4 matching layer that matches the bulk permittivity of ZrO 2 to air. As expected, the λ/4 layers reduce the reflections in part of the 13-18 GHz band but produce high reflection in other parts. The second approach is a GRIN lens with integrated tapered matching layer to match phase and impedance simultaneously. Three tapering methods are studied (exponential, Klopfenstein, linear) for impedance matching. Analytical expressions of the minimum thickness and permittivity distribution are derived. The lens is discretized for print and three types of unit cells are proposed to create a wide range of permittivities ranging from bulk ceramic to air. A ZrO 2 lens prototype printed with an XJet Carmel 1400 is measured and results show good agreement with simulations, including gain performance equivalent to a horn of 2.4x longer length. The measured gain and beamwidth of the lens are 5.4dB higher and 52 • narrower than those of the shortened horn alone at 15 GHz, respectively.
