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.

The present technology fulfills the requirement of high data rate and high channel capacity using multiple input multiple output (MIMO) technology. The MIMO capacity of the system is increased linearly but due to the multiple antennas placed near to each other, problem of mutual coupling exists, which degrades the maximum achievable performance of the system. The problems of multipath propagation can be solved using MIMO system. The isolation improvement methods decrease the mutual coupling among antenna elements, and improve the gain and efficiency of the system. In this paper, decoupling network isolation approach, parasitic element approach, defected ground structure, Neutralization line, isolation improvement based on metamaterials, isolation improvement using PIN diode, varactor diode, and feeding structure have been incorporated, and their merits and demerits have been discussed. The effect of different permittivity material on antenna parameters has also included.

“…However, all the above-mentioned structures have only linearly polarized (LP) radiating elements. Recently, use of single or multiple circularly polarized (CP) radiators along with conventional LP radiators is garnering serious attention among MIMO system designers [13]- [16]. It is shown in [13] that application of CP antennas for MIMO transmission instead of conventional cross linear polarization antennas will emerge a promising method in outdoor to indoor environments.…”

“…In [14], a two element MIMO antenna system with polarization and pattern diversity (LP/CP type) is reported, where compactness is achieved in the proposed design at the cost of inter-element isolation in the operating band. CP antenna arrays are used to achieve the desired diversity characteristics in [15] and [16]. In this letter, a compact three-element MIMO antenna system ( Fig.…”

In this paper, a three-element compact Multiple Input Multiple Output (MIMO) antenna system having both pattern and polarization (linear/circular) diversity is proposed. The proposed MIMO system consists of a chamfered edge square patch antenna with an offset feed that provides circular polarization in broadside direction. Furthermore, two printed dipole antennas are placed adjacent to it for providing linearly polarized end-fire radiation. The three-element MIMO antenna system exhibits good isolation (> 15 dB) without the use of any separate decoupling structure. The match between the simulated and measured results on fabricated antenna prototype suggests that the proposed antenna can be a good candidate for pattern and polarization diversity MIMO applications in the 5.8 GHz WLAN frequency range.
