“…These PDAs require a multi-port assistant for smarter connectivity, which is why multi-port antennas are introduced to proliferate its data connectivity in a compact wireless integrated portable system [19][20][21]. Thus, multiple-input-multiple-output (MIMO) proves to be the best solution [22][23][24][25][26][27][28]. For portable handheld smarter devices, usually the dual/tri-port antenna systems are feasible [29,30].…”

In this article, we present a compact and efficient diametrically-fed dual port fractal UWB MIMO antenna for portable handheld wireless devices. The electromagnetic behaviour on conducting body is analyzed through classical approach based characteristics mode analysis (CMA). Their intrinsic characteristics are explored on the basis of (a) modal surface current distributions, (b) narrow/broad bandwidth capability, and (c) radiation potentials. Concurrent analysis is persuaded on a diametricallyfed dual-port fed fractal conducting surface, which provides interesting facets on the combinatory effect of electromagnetic performance and physical behaviour on metallic radiator, metallic ground planes (unconnected/connected) and combination of two aforementioned metallic compact geometries. Theoretical insights are investigated for essential/non-essential modes existing in proposed geometry. The investigation through CMA also gives plethoric information on the feed location of antenna on modal surface currents and similar trends to capture its radiation potentials on the current nulls existing in the physical body. A broad classification of modes is explained, covering the CMA modal dynamics such as (a) characteristics angle (CA), (b) eigenvalues (EV), and (c) modal significance (MS). These additive parameters in general reflect the resemblance of Q-factor ≈ B.W. for narrowband/wideband traits, electrically/magnetically coupled energy behaviour, and radiative potential for far-field propagation. Thus, in a nutshell , it can be concluded that 'CMA provides physically intuitive guidance for the analysis and designing of antenna structures'. To support the findings highlighted in this particular study, a concise review about the theory of characteristic modes and the practical examples that use such concepts are taken into consideration.

“…Diversity techniques such as spatial, pattern, and polarization are used to encounter multipath interference. Therefore, a multiple-inputmultiple-output (MIMO)/diversity antenna could be advantageous for vehicular communications [6][7][8][9]. But, the main problem with MIMO antennas is high coupling between resonating elements.…”

A quad-element multiple-input-multiple-output (MIMO) antenna with ultra-wideband (UWB) performance is presented in this paper. The MIMO antenna consists of four orthogonally arranged microstrip line-fed hexagonal monopole radiators and a modified ground plane. In addition, E-shaped and G-shaped stubs are added to the radiator to achieve additional resonances at 1.5 GHz and 2.45 GHz. The reliability of the antenna in the automotive environment is investigated, with housing effects taken into account. The housing effects show that the antenna performs consistently even in the presence of a large metal object. The proposed MIMO antenna has potential for various automotive applications, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X), intelligent transport system (ITS), automatic vehicle identifier, and RFID-based electronic toll collection.

“…From the available literature, it is observed that the previously reported structures have either large dimensions or bandwidth unable to cover UWB frequency spectrum or beyond it. In the available literature, antenna designers [24–33] have used FR-4 epoxy substrate due to its low cost. On the other side, some researchers have avoided it due to its losses at millimeter range frequencies [34, 35].…”

Two configurations of a modified feather-shaped antenna element are proposed for super wideband (SWB) multiple-input multiple-output (MIMO) applications. The antenna element geometry comprises of a circular slot-loaded feather-shaped radiator and rectangular notch-loaded quarter elliptical coplanar waveguide ground plane. An operating bandwidth of 4.4–51.5 GHz with inter-port isolation, S21 ≥ 15 dB for spatial diversity configuration, and 3.8–51.5 GHz with S21 ≥ 15 dB in pattern diversity configuration are achieved. The footprints of the antenna configurations are 17 × 33 and 31 × 31 mm2. Both configurations exhibited an envelope correlation coefficient of <−20 dB. The proposed MIMO configurations are fabricated and experimentally validated. The designed antenna configurations are SWB and compact.
