“…With the partial removal of ground plane on the bottom plate, the bandwidth is enhanced and ECC below 0.5 is achieved. The common radiator with four port MIMO antenna, discussed in [ 84 ], consists of a common radiating element and a square ring ground plane. Good isolation is achieved through space diversity and by etching the stubs in the ground plane, to achieve isolation of less than −15 dB and measured return loss of −10 dB is achieved for frequency range from 4.5 GHz to 7 GHz.…”

In response to the increasing demand for voice, data, and multimedia applications, the next generation of wireless communication systems is projected to provide faster data rates and better service quality to customers. Techniques such as Multiple-Input–Multiple-Output (MIMO) and diversity are being studied and implemented to meet the needs of next-generation wireless communication systems. Embedding multiple antennas into the same antenna system is seen as a promising solution, which can improve both the system’s channel capacity and the communication link’s quality. However, for small handheld and portable devices, embedding many antennas into a single device in a small area and at the same time providing good isolation becomes a challenge. Hence, designing a shared antenna system with multiple feed ports with equivalent or better performance characteristics as compared to the approach of multiple antennas with multiple feed ports is a promising advantage which can reduce the size and cost of manufacturing. This paper intends to provide an in-depth review of different MIMO antenna designs with common radiators covering various antenna design aspects such as isolation techniques, gain, efficiency, envelope correlation coefficient, and size, etc. There is also a discussion of the mathematical concepts of MIMO and different isolation techniques, as well as a comparative analysis of different shared radiator antenna designs. The literature review shows that only very few antennas’ design with common radiator have been suggested in the available literature at present. Therefore, in this review paper, we have endeavored to study different antennas’ designs with common radiator. A comparison is provided of their performance improvement techniques in a holistic way so that it can lead to further develop the common radiator multiport antenna systems and realize the promising advantages they offer.

“…Paramayudha et al designed a four‐port diversity patch antenna to achieve a considerable amount of isolation by changing the orientation as of 90° between each consecutive port . A single radiator with four perpendicular feeding ports was designed, introducing radiation stubs and ground stubs to improve the impedance matching and isolation under −25 dB. Although a coplanar stepped impedance resonator (CSIR) and a rectangular slot line resonator (RSLR) are used to construct two bands with isolation degrees higher than 30 dB and 40 dB, respectively .…”

The work presented in this article is focused on the design of an omni‐directional and dual‐frequency antenna for multiple input multiple output (MIMO) applications. The proposed antenna consists of a monopole with a pair of L‐shaped strips and a butterfly‐like coupling slot, excited by a coplanar waveguide and a proximity coupling, respectively. Using two completely different elements and exciting multimode orthogonal characteristics current, high isolation for two ports is achieved. To improve the stability of input impedance, a gradient arc structure between the microstrip line and monopole element is adopted. The designed MIMO antenna provides port isolation of better than −20 dB and envelope correlation of lower than 0.02, at two resonant frequencies covering WLAN/WiMAX bands.
