“…16 indicates that the antennas have orthogonal radiation patterns which reduce signal correlation between antenna elements and enhance the antennas' input impedance matching. Thus, the combination of closely spaced antennas in a compact configuration with orthogonal radiation patterns may lead to high antenna isolation characteristics [23].…”

Abstract-This paper presents a new design approach for compact orthogonal broadband printed multiple-input multiple-output (MIMO) antennas based on a coplanar waveguide (CPW)-fed hexagonalring monopole antenna (HRMA) element. The design procedure of the basic radiating element is initiated from a stripline (SL)-fed circular monopole antenna (CMA). Then various antennas involved in the design evolution process are introduced to attain a compact CPW-fed HRMA. This basic antenna element has a compact size of 13 × 10 mm 2 , 50% smaller than SL-fed CMA, and a prototype of this antenna is built and tested. Based on HRMA element, compact two-and four-element MIMO antenna systems are designed, fabricated and experimentally demonstrated for 5-GHz ISM band operation. The MIMO antenna systems use orthogonally configured of identical closely spaced HRMA elements, with CPW-fed printed on one side of the substrate to achieve good isolation. Design simulation is carried out with the aid of Computer Simulation Technology Microwave Studio (CST MWS) and confirmed with High Frequency Structure Simulator (HFSS). The experimental results are in close agreement with the simulated ones, which validates the design principle. Based on experimental results, the two MIMO antenna systems have an impedance bandwidth of more than 2 GHz, good isolation of less than 15 dB, and a low envelope correlation coefficient of better than −26 dB across the frequency band of (4-6 GHz), which are suitable for 5-GHz MIMO applications.

Abstract-An E-shaped printed monopole antenna with loaded resonant elements suitable for pentaband multi-input multi-output (MIMO) application is proposed. The simple E-shaped monopole antenna results in a single resonance, and by loading the vertical arm of the antenna with narrow slots and stubs, a multi-band antenna can be obtained. The slots so placed on the antenna create L-shaped resonance paths which are multiples of λ g /4, and stubs resonate at λ g /4. The antenna is designed for operation over the UMTS, WiMAX and WLAN frequencies 2.1, 2.5, 3.5, 5.2, 5.8 GHz. A two element array of such antennas with close spacing of λ g /15 is suitable for MIMO application. The array has low mutual coupling, low envelope correlation, high efficiency and good radiation patterns over all five frequency bands. Simulation and measurement results are compared and discussed.

“…Fork-like stub and short strip are used to weaken the mutual coupling between elements. Four-element MIMO antenna systems are also developed [7][8][9]. In [7], the system is designed for a 2.45-GHz ISM band operation, and complementary split-ring resonator (CSRR) loaded on the ground plane is used for antenna miniaturization.…”

“…In [7], the system is designed for a 2.45-GHz ISM band operation, and complementary split-ring resonator (CSRR) loaded on the ground plane is used for antenna miniaturization. System reported in [8] is capable of multiband performance, and the high value of isolation between elements is due to the split in the individual ground plane of each element. Moreover, large size (58 mm × 110 mm) and decoupling structures are used in [9].…”

“…The system can be used for LTE 2300 and 2.45 GHz ISM band applications. Compared to the aforementioned systems [3][4][5][6][7][8][9], the proposed four-antenna system does not need any specially designed decoupling structures and has a higher than 15 dB isolation throughout the working band. Correlation coefficients and radiation pattern show that this antenna system is suitable for nowadays portable devices.…”

Abstract-A novel four-element multiple-input-multiple-output (MIMO) antenna system for LTE 2300 and 2.45 GHz ISM applications is presented. The total size of the proposed MIMO antenna system is 34 mm × 18 mm, and the whole antenna system has a wide working bandwidth of 350 MHz (2.19-2.54 GHz). The measured isolation between antenna elements is higher than 15 dB with a close edgeto-edge separation of 0.03λ. Correlation coefficient of the MIMO antenna system is lower than 0.12, which can meet the requirements of 4G wireless systems.
