“…Moreover, more variations and nulls in the radiation patterns can be seen for frequencies in the higher operation band. [1,3,5,11,13] in terms of isolation structure, number of frequency bands and MIMO antennas, antenna distance, size, and isolation are listed in Table 3. The results show that the proposed antenna with narrow size and satisfying isolation is a good candidate for MIMO system applications.…”

In this article a thin hybrid multiband printed loop antenna is presented for application in multiple-input multiple-output (MIMO) systems. The proposed antenna has several advantages; for example, the pseudofilter feature of the proposed antenna is one of this antenna's advantages. Because of the antenna's width ( 9.5 mm), it can be used on the edges of the board. The first resonant frequency is generated by the original loop of the antenna. Incorporation of different embedded components, i.e. a subsidiary loop, extended ground-traces, parasitic patch, and the slits, results in the proposed antenna resonating as a multiband antenna. This antenna is adjusted in such a way that it resonant in WLAN ( 2.4 , 5.2 , and 5.8 GHz) and WiMAX ( 3.5 GHz) bands. Four antennas are used as a MIMO system that are sequentially and perpendicularly placed along the edges of the board. In conclusion, the antenna design is confirmed according to simulation results obtained from the constructed prototype and associated measuring results.

A method to significantly increase the gain of a bow‐tie antenna based on metamaterial concept is presented. The μ‐negative feature of the proposed two‐sided planar metamaterial (TSPM) structure is investigated by retrieving its constitutive parameters from the S‐parameters. The proposed structure consists of six slabs that are loaded with a 3 × 3 array of TSPM unit cells, which are embedded in azimuth plane of a modified bow‐tie antenna vertically. The TSPM unit cells provide a medium of low effective permeability. The dimensions of the slabs are 30.6 × 20.6 mm2 at 7 GHz. To show the adaptability of the proposed high‐gain antenna, the structure was designed to cover H‐band applications (6‐8 GHz). Consequently, a small antenna is designed in comparison with initial bow‐tie structures. The corresponding return loss of the antenna is better than 10 dB over 6 to 8 GHz. The proposed metamaterial antenna was manufactured and its characteristics measured to verify the proposed idea. Good agreement between the measured and simulated data is obtained. Maximum gain measured of the antenna is 10.21 dB at 7.5 GHz, constituting a maximum gain enhancement of 7 dB for H‐band in comparison with a bow‐tie antenna without any metamaterial structures.

A four port compact low profile planar MIMO antenna with meander line radiators and with polarization diversity effect has been proposed to cover 5.8 GHz wireless local area network application. The proposed MIMO antenna has −10 dB impedance bandwidth of 1.4 GHz (5.3–6.7 GHz) along with the compact size of 38 × 38 mm2 and an envelope correlation coefficient (ECC) of less than 4 × 10−4 in the whole band. The proposed antenna resonates at 5.8 GHz frequency, having return loss of −43.2 dB. The isolation between diagonal and opposite ports is more than 10 and 12 dB, respectively, in the presented frequency band. The total active reflection coefficient frequency response shows more than 1.0 GHz of bandwidth in the whole band. The antenna gain is more than 4.0 dBi in the operating frequency band. The radiating elements are very close to each other to make the design very compact.
