“…The primary design metrics used for investigating UWB MIMO antennas are compact size, filtering out existing narrow bands, and wideband isolation simultaneously. The literature reveals many approaches for attaining antenna downsizings, such as high ε and μ material, meander lines on radiating and ground planes, modifying radiating and ground plane structures, metamaterial loading, and loading lumped elements 8–10 . The antenna miniaturization significantly impacts the antenna's mutual coupling, which degrades overall antenna performance.…”

A novel two-and four-port antenna structure are proposed to achieve improved isolation and operate in the ultrawideband (UWB) frequency range.The projected designs comprise a hybrid circular and rectangular embedded UWB antenna with a partial ground plane. The alteration of the radiating and ground planes modifies the current flow and aids in realizing a broader bandwidth. The dual-band notches are created on UWB using slot and stubs. The U-shape slot on the feedline neutralizes the current flow at 5.2 GHz, and a pair of symmetrical H-shape stubs across the feedline couples the current flow from the feedline to stubs at 7.4 GHz frequency, and negligible current reaches the radiator. The dual-band notch UWB antenna is reproduced to create two-port and four-port MIMO antennas with a less than quarter wavelength spacing. Using a deficient ground structure, better isolation between the interelements is achieved. The projected two-and four-port design has overall physical geometry of 0.2λ Â 0.4λ Â 0.02λ and 0.5λ Â 0.4λ Â 0.02λ and provides a measured impedance bandwidth between 3.3-12.8 and 3.1-12 GHz, respectively. The distinctive feature of both antenna designs is incorporating simple and effective defective ground structures as decoupling structures in the ground plane to generate better than 25 dB isolation across the operational spectrum. The current between the interelement is suppressed via the ground plane, leading to mutual coupling reduction. In addition, complete MIMO diversity parameters and time-domain characteristics are explored, and the findings show that the proposed designs are appropriate for wireless applications.

In this article, a miniaturized pentagonal slot antenna (PSA) with a Meander Koch Defected Ground Structures (MK-DGS) and metamaterials (MTM) is proposed for 5 GHz WLAN application. Initially, a Meander Koch DGS was used to lower the resonant frequency of the basic PSA, from 13.1 GHz to 5 GHz. The proposed antenna has been 61.83% miniaturized, close to an electrically small antenna. The performance characteristics of a basic PSA using MK-DGS and MTM superstrate, which improves efficiency, directivity, and peak gain, are also discussed. An antenna with dimensions of 15×15 mm 2 (or) 0.25λ 0 × 0.25λ 0 mm 2 at a thickness of h 1 = 1.6 mm is designed, fabricated, and tested on an FR4 epoxy substrate, and its impact on size reduction performance is evaluated. The gain at 5 GHz is increased from 3.15 to 7.84 dBi by introducing an MTM superstrate made of RT Duriod at a thickness of 1.575 mm above the miniaturized PSA at 17 mm. Test results of the prototype model are corroborated by the simulated results of the proposed model.

The paper presents a 1 × 2 B-shaped antenna array for dual-band operation at 4 and 8 GHz. The antenna design consists of a rectangular patch with two annular-strip lines fabricated on the top layer and finite ground plane on the bottom layer. The array is formed by designing an optimum T-shaped microstrip line for impedance matching. The dimensions of the antenna array are 78 × 36 × 1.6 mm3. Full-wave simulations have been conducted and the measured results are in good consent with the simulated results. The measured impedance bandwidth (reference −10 dB) has been observed at 3.84–4.16 and 7.78–8.38 GHz. Measured peak gain and radiation efficiency at 4 and 8 GHz are 8.3, 9.4 dB and 82.5 and 81.2%, respectively.
