The wireless technology resides at 5G global standard wireless communication. This standard enhances the network capacity, network coverage, lower latency and enormous bandwidth by increasing the operating frequencies of the communication standards. 5G standard promises to deliver a speed of 500 times faster than 4G by utilizing the technology such as massive MIMO, small cell, beam forming and full duplex technology. The higher operating frequencies leads to the path loss constrains and the device compact also one of the issues arises in the handheld wireless communication devices or massive machine type communications. To overcome these issues an effective antenna has to be designed for the new generation wireless standards. Most commonly used handheld communication devices, IoT devices and massive machine type communication uses microstrip patch antenna as radiating elements and the substrate materials associated with these antennas plays a key role for the development of an antenna. In this paper, investigations on six different substrate materials were done for the design of MIMO antenna. A rectangular microstrip antenna was designed under the operating frequency of 28 GHz using six different substrate materials such as Taconic TLY-5A,

“…However, the above designs suffer from large sizes [ 7 ], narrow bandwidth [ 8 , 9 ], and complicated designs [ 11 ]. Other techniques include using split ring resonators as monopoles for bandwidth enhancement [ 13 ] and circular ring monopoles with circular parasitic elements for bandwidth enhancement [ 14 ].…”

A novel 4-element Multi-Input Multi-Output (MIMO) array antenna is proposed for Dedicated Short Range Communications (DSRC), Wireless Local Area Network (WLAN), and X-band applications. The proposed antenna is a microstrip antenna that consists of a simple square patch as radiating element with a defected ground structure (DGS). Dimensions of the proposed antenna are very compact with size 40 × 48 × 0.8 mm 3 . It operates from 5.6-6.1 GHz (DSRC/WLAN) and 8.7-10.8 GHz (X-band) with impedance bandwidths (S 11 <= −10 dB) of 500 MHz and 2.1 GHz, respectively. The isolation between elements of MIMO is also greater than 25 dB in the operating bands. Antenna performance parameters are investigated at 5.9 GHz and 10.5 GHz center frequencies and computersimulated, and experimentally measured characteristics are found to be satisfactory. A peak gain of 4.8 dB is achieved, and radiation efficiency is also greater than 75% in operating bands. Envelope Correlation Coefficient (ECC) is less than 0.05, and Diversity Gain (DG) is very close to 10. Group delay among the MIMO elements is below 2.7 ns, and Channel Capacity Loss CCL is also below 0.4 bits/sec/Hz. Therefore, the proposed 4-element MIMO antenna is suggestible for DSRC/WLAN and X-band applications.
