“…The proposed design achieves wideband performance extending from 26 to more than 39 GHz. The operation bandwidth, gain, and MIMO parameters of the proposed antenna is higher than MIMO array reported in References [11,[13][14][15][16][17][18]. Therefore, the proposed antenna can be employed for various MIMO 5G systems.…”

In this paper, an enhanced upper band 5G multiple-input multiple-output (MIMO) array is presented. The proposed array is based on a wide band LPDA antenna loaded with epsilon near zero (ENZ) index metamaterial. The metamaterial cells result in more than 3 dBi gain enhancement. In addition, multiples metamaterial cells arrangements are studied including straight, concave, and convex rows. The array covers a wideband of MMW frequencies extending from 26 up to 39 GHz. The LPDA antenna element design consists of alternating five arms printed on RO5880 substrate. All of the dipole arms are uniformly placed along parallel microstrip feeding transmission lines on both sides of the substrate. The main feeding line is placed over a partial ground plane at the backside of the substrate. The MIMO-LPDA array exhibits stable radiation characteristics over the operating band. A maximum realized gain of 11 dBi is achieved at 36 GHz for a single element radiator. In addition, essential MIMO performance indicators such as Envelope Correlation Coefficient (ECC), Diversity Gain (DG), and Channel Capacity Loss (CCL) are examined and determined to fulfill the needed standard of ECC, DG, and CCL. The fabricated prototypes of both the single antenna element and the MIMO array show very good agreement with simulated results.

“…To fulfill their task, textile antennas should resemble common textile materials in flexibility, lightweight, and aesthetics yet show good radiation efficiency and impedance matching, mechanical durability, water resistance, etc., as well as allow implementation of technologies such as Multiple-Input Multiple-Output (MIMO) [ 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. As textile antennas are designed to operate on the human (user’s) body, another important requirement are maximum exposure limits to electromagnetic (EM) fields, i.e., maximum Specific Absorption Rate (SAR), which should not be exceeded [ 12 , 13 , 14 ].…”

One of the major challenges in the development of wearable antennas is to design an antenna that can at the same time satisfy technical requirements, be aesthetically acceptable, and be suitable for wearable applications. In this paper, a novel wearable antenna is proposed—textile realization of a slotted waveguide antenna. The antenna is realized using conductive fabric to manufacture the walls of a rectangular waveguide in which the slots were cut out. All connections and cuts are sewn with conductive thread taking over advantages of the traditional process of manufacturing textile objects. The developed slotted waveguide array prototype, containing three slots and designed for operation in the 5.8-GHz ISM band, is experimentally characterized and compared to an equivalent metallic antenna. The achieved operating bandwidth is larger than 300 MHz in both cases. The measured gain of a textile slotted waveguide array is around 9 dBi with a radiation efficiency larger than 50% in the whole operating bandwidth, i.e., the textile array showed a 2 dB lower gain in comparison to the metallic counterpart. The gain is stable in the whole bandwidth and the radiation patterns do not differ. The results demonstrated that such textile antennas are suitable for body-centric communication and sensor systems and can be integrated into clothing, e.g., into a smart safety vest or into a uniform. Further analysis of various realizations of slotted waveguide antennas is presented showing that different versions of the proposed antenna can be used in all three off-body, on-body, and in-body communication scenarios.
