“…The results of the proposed MIMO antenna and the recent MIMO antennas are summarized in Table 3. In [20], although there is a large bandwidth percentage; the isolation of antenna is very high; the gain of antenna is only 6 dBi. Similarly, there is a high isolation in [21], and the gain of antenna is not good (5.3 dBi).…”

This paper investigates a low-profile Multiple Input Multiple Output (MIMO) antenna with enhanced gain based on Defected Ground Structure (DGS). The proposed antenna consists of two sets of four elements (2 × 2), and it is yielded at the central frequency of 5.5 GHz for Wireless Local Area Network (WLAN) applications. Being on RT5880 with height of 1.575 mm, the overall dimensions of MIMO antenna and single array are 145 × 88 × 1.575 mm 3 and 75 × 82 × 1.575 mm 3 , respectively. To get high gain and low mutual coupling for antenna, a Defected Ground Structure (DGS) is proposed and integrated on ground plane. At 5.3 GHz, the gain of antenna achieves approximately 9.5 dBi while mutual coupling level is under −20 dB. Besides, the MIMO antenna witnesses a radiation efficiency of 93%. The measurement results are compared to simulation ones to verify the performance of the proposed antenna.

“…In [9], an antenna with size of 150 × 150 mm 2 consists of four meandered loop elements, two of them cover the bands of 699-798 MHz and 2.3-2.5 GHz, and the remainder operate on 1.7-2.0 GHz, 3.5-4.0 GHz, and 5.3-6.0 GHz. An antenna system with 6 elements each with size of 30 × 30 × 12.9 mm 3 was proposed in [10] for 5 GHz applications. In [11], four monopole elements on a 120 × 140 mm 2 common patch were designed for operating over frequency range of 1.85-2.95 GHz.…”

A novel and compact scalable antenna system is designed for multiport applications. The basic design is built on a square patch with an electrical size of0.82λ0×0.82λ0(at 2.4 GHz) on a dielectric substrate. The design consists of four symmetrical and orthogonal triangular notches with circular feeding slots at the corners of the common patch. The 4-port antenna can be simply rearranged to 8-port and 12-port systems. The operating band of the system can be tuned by scaling (S) the size of the system while fixing the thickness of the substrate. The antenna system withS: 1/1 in size of103.5×103.5 mm2operates at the frequency band of 2.3–3.0 GHz. By scaling the antenna withS: 1/2.3, a system of45×45 mm2is achieved, and thus the operating band is tuned to 4.7–6.1 GHz with the same scattering characteristic. A parametric study is also conducted to investigate the effects of changing the notch dimensions. The performance of the antenna is verified in terms of the antenna characteristics as well as diversity and multiplexing parameters. The antenna system can be tuned by scaling so that it is applicable to the multiport WLAN, WIMAX, and LTE devices with port upgradability.

“…The large size of the antenna along with power divider circuit makes the overall design very intricate to deal with. A six-port multiple-input-multiple-output antenna system for 5-GHz WLAN access points application is proposed in [12]. It has a good isolation performance, but the aperture coupled antennas mounted on a hollow metal structure backed by a quarter-wave-length choke make the antennas complex for the given functionality, and the gains of the different antennas also show a variation from 3.5 to 5 dBi.…”

This paper demonstrates a three-port coaxial fed antenna system for wireless local area network (WLAN) access points, consisting of two dipoles and a patch, radiating at 5.2 GHz with impedance bandwidth of 150 MHz. The antennas are designed for pattern diversity in the end-fire and broadside orientation with an individual gain of 4.5 dBi, which is further enhanced to 6 dBi after integrating with unit-cell structures. The gain enhancement for individual antennas is achieved by strategically integrating transmission type and reflective type sub-wavelength structures for patch and dipoles, respectively. The realized ground plane is shared among the three antennas. The measured results show that the return loss of the antennas is unaffected by the unit-cell loading and has an isolation of less than 26 dB throughout the band and across the ports for a port-to-port distance of 0.25λ.
