In this paper, the metamaterial based rectangular microstrip patch antenna is proposed and designed for THz applications. The circular split ring resonator is implemented as metamaterial. By incorporating metamaterial in the conventional microstrip patch antenna, the size is reduced and the performance of antenna is improved. The proposed antenna has the dimensions of 180 × 212 ×10 µm 3 which is designed on Quartz substrate which is fed by microstrip line feed technique. Additionally, the performance of the metamaterial antenna is analyzed by varying unit cell gap size and thickness. The antenna resonates at 1.02 THz which gives the return loss of-65 dB. Thus, the proposed antenna can be utilized in THz region.

“…Various antenna designs with different operating frequency bands such as narrowband, wideband and dual/triple band [5] have used these approaches. Methods reported include using parasitic elements between the antennas [6,7], junctions and branches in the form of T-shape [8,9], defected ground structures (DGS) [10,11], stubs [11,12], neutralization lines (NL) [13][14][15][16][17] and metamaterial resonators [18][19][20][21][22][23][24][25].…”

A compact dual-band (2×2) MIMO antenna that operates at 2.4GHz, 3.4GHz and 3.6GHz for wireless local area network (WLAN) and Sub-6GHz 5 th generation (5G) applications is demonstrated in this paper. A metamaterial resonator method for improving the isolation is applied by introducing four SRRs resonating at 2.4GHz between the adjusting elements. The overall size of the antenna is 46x54x1.6 mm 3. The proposed antenna achieves impedance bandwidths from 2.15GHZ to 2.75GHz and from 3.1GHz to 4.4 GHz for the two bands respectively. The reported isolation is 30 dB around the 2.5GHz band and 20 dB around the 3.5GHz band. The features of the proposed MIMO antenna are illustrated in terms of s-parameters, ECC, TARC, CCL, DG and antenna radiation patterns. These parameters are analyzed carefully and the consequences show that the proposed MIMO antenna is suitable to work in the intended frequency bands.

“…To counter the issues like high path loss and interference at 28-GHz, high gain antennas designed with MIMO and beamforming capabilities are proposed [2]. Various MIMO antennas for 5G applications have been proposed in [3][4][5][6][7][8][9]. In [10], a Ka-band MIMO antenna is proposed with a gain about 9.5-11 dBi and has a good isolation of 20 dB between the ports in the frequency range from 26.8 to 28.4 GHz, but this antenna occupies good amount of space (39.8 mm × 33.4 mm) on the board.…”

In this letter a four-port multi-input-multi-output (MIMO) antenna for 5G applications is proposed. This antenna is compact with a size of 11 mm × 31 mm excluding feed lines. The radiation patterns of the antenna show pattern diversity in the azimuthal plane, and each antenna element has an end-fire gain about 10 dBi by employing an array of metamaterial unit cells. The isolation between the antenna elements with edge to edge separation < λ 0 /5.5 at 28 GHz is enhanced by trimming the corners of the rectangular high refractive index metamaterial region along with a ground stub between antennas. The proposed antenna is fabricated, and each antenna element has return loss, S nn < −10 dB with isolation, S nm > 21 dB in the frequency range 26 GHz to 31 GHz, which makes this antenna potential candidate for MIMO application at 28 GHz band enabling 5G cellular communications.
