“…The bow-tie aperture four port MIMO antenna was designed for Hexa bands using optimization techniques. The maximum efficiency is 90% at the 2.4 GHz band [1].The brand-new MIMO antenna structure is resonant from 2.25 to 2.87 GHz and implemented with four printed dipoles and a decoupling element. The self-isolated MIMO antenna provides better radiation characteristics and more than 19 dB isolation.…”

This research work describes a compact four-port multiple input multiple output (MIMO) antenna using defective ground structure (DGS), and it perfectly supports the n77, n78, and n79 frequencies in 5G new radios (NR) bands. It can cover a wideband from 3.4 to 5.4 GHz with good impedance matching. The pair of antenna elements are orientated opposite to another pair with DGS. Due to this technique, it has minimal complexity, is less expensive, and improves isolation. It has also improved the frequency band's reflection coefficient and range using MIMO antenna with different stub lengths. Because it is less expensive, FR-4 substrate is used in the implementation of all antennas. Each antenna element has two identical stubs linked to the primary radiator. On the primary radiating element, a ''HI'' slot is created. The partial ground enhances impedance matching and radiation properties throughout the targeted band. <span>The total dimensions of the four-port MIMO antenna are 46×30×1.6 mm<sup>3</sup>. The array elements' mutual coupling in the simulation is -14 dB. The ECC value is below 0.01, and the diversity gain (DG) is less than 10 dB. The suggested designs' measured gain ranges from 10 to 11.0 dB, and the radiation efficiency is nearly 91%.</span>

“…Similarly, many antennae [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] were developed with different techniques to increase the isolation, decrease the mutual coupling, or enhance the parameters like ECC, but all of these antennas have a limitation in terms of throughput and ECC which is necessary for the proposed applications of AWS and WBAN. Here we propose a MIMO antenna with low coupling and ECC without any additional structure in the antennas with dual frequencies of operation.…”

A Multi-Input Multi-Output (MIMO) dual-band antenna useful for advanced wireless services (AWSs) and wireless body area network (WBAN) applications is presented. To have dual bands of operation two techniques were used namely, Defective Ground Structure (DGS) and slotted patch. The lower operating band is spread over 108 MHz from 2.106 GHz to 2.214 GHz which covers AWS, UMTS, and LTE bands. The upper operating band is spread over 221 MHz from 4.141 GHz to 4.362 GHz which covers the WBAN band. The lower operating band is the result of perforation in the patch and inverted T-shaped ground, and the upper operating band is due to the two rectangular slots placed diagonal to each other in the patch and perforations in the ground. High isolation among MIMO elements is observed through a low Envelope Correlation Coefficient (ECC) of 0.0004. The design of a 2 × 2 MIMO antenna is realized using FR4 material with a size of 70 mm × 70 mm × 1.524 mm and Ansys HFSS tool. A high level of correlation between simulated and experimental results is observed which enables the presented MIMO antenna to be perfect for the proposed AWS and WBAN applications.

Different structures of microstrip antenna optimization using different algorithms are the important field of wireless communications. Rectangular microstrip antenna, inverted E-shaped antenna, tulip shaped antenna are some examples of microstrip antennas. The antenna dimensions are optimized by different algorithms. The operating frequencies for different antenna structures depend on antenna dimensions. The frequency of operation is 3-lS GHz for rectangular antenna, IMT-2000 for invelted E-shaped antenna, 8 to 12 GHz for tulip shaped antenna, 2.16 GHz for miniaturized antenna structure. The dimensions of microstrip antennas are modified to get minimum reflection coefficient maximum gain and bandwidth. The dimensions are modified using different algorithms such as evolutionary algorithm, particle swarm optimization (PSO), artificial neural network (ANN), and genetic algorithms (GA).
