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.

“…Conventional dual-polarized antennas generally can be achieved by microstrip patch antennas or dipole antennas, and each has its own advantages and disadvantages. The microstrip patch antennas [1][2][3] have a low-profile characteristic, but their application in the base station is restricted because of their narrow bandwidth and big loss. The dipole antennas [4][5][6] can always be designed reasonably to meet the current mobile communication requirements of bandwidth.…”

Abstract-Artificial magnetic conductor (AMC) is a periodic structure with in-phase reflection, which can be used in dual-polarization dipole antenna to reduce profile height. In this study, a low-profile dual-polarized dipole antenna with an AMC reflector is proposed by improving the AMC structure. The antenna consists of a pair of orthogonal planar dipoles with U-shaped slots, two T-shaped feeding lines, and an AMC reflector. The overall height is 0.132λ 2.2 GHz . Experimental results show that the proposed antenna has a wider bandwidth than other antennas of the same type. The impedance bandwidth of this antenna is 52% (1.65 GHz to 2.81 GHz), and the proposed antenna also has the advantages of low profile, high port isolation (< −30 dB), and low cross polarization (< −27 dB). These features can meet the current needs of the telecommunications industry.

“…The key challenge of the duplex antennas is to improve ports isolation. There are several methods to eliminate the mutual interference between the transmitting and receiving ports such as employing multilayer feeding structures [1,2], using different feeding methods [3,4], or adding filtering structures to the feeding lines, like defected ground structures (DGS) [5,6], electromagnetic band-gap structures (EBG/PBG) [7,8], and defected microstrip structures (DMS) [9]. Although these antennas can realize duplex function and high isolation between ports, they usually suffer from large size and high cost.…”

Abstract-In this paper, a 2 × 1 duplex antenna array with small frequency space and high isolation between transmitting and receiving bands is presented. The duplex antenna array element consists of a pair of radiating patches for bidirectional radiation, a set of microstrip resonator and H-slot resonator coupled to the patches for transmitting, and the other set of microstrip and H-slot resonators coupled to the patches for receiving. The H slots are designed for the operations of coupling and the elements of the bandpass filters. The two antenna elements of the 2 × 1 array are connected by transmitting and receiving channels microstrip power-split resonators. The array achieves a compact size and high performances in terms of high isolation and small Tx-Rx frequency space. Higher than 30 dB and 40 dB ports isolation at 1.94-1.99 GHz and 2.43-2.52 GHz is realized. And the Tx-Rx frequency space Δf = (f r − f t ) is smaller than 0.23 times of the central frequency (f r + f t )/2.
