Abstract-In this paper, the band-notched characteristic inheritance in ultra-wide band (UWB) multiple input multiple output (MIMO) antenna array design is studied. First, the structure parameters and return loss of a monopole antenna are optimized to obtain desired UWB property. Then, the bandnotched characteristic is realized in 7.9-8.4GHz by using the rectangle split ring resonator (r-SRR). Furthermore, this UWB antenna is utilized to form a MIMO antenna array based on quasi-self-complementary antenna technique. Finally, the simulation results show that on the one hand, the band-notched property of the unit antenna can be inherited by the antenna array; on the other hand, the bandwidth of the stop band for antenna array is increased by about 66% compared with that of the antenna unit.

“…WLAN and WiMax bands were achieved by using slotted ground structure and metamaterial rectangular split ring resonator. Many MIMO antennas have been proposed to reduce the mutual coupling for UWB systems [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In [4][5][6][7][8], various decoupling structures have been inserted between two antenna elements to enhance wide band isolation.…”

“…Considering the fact that many MIMO antennas have been proposed, there are only few papers of MIMO technique in UWB systems. For those which could cover the whole UWB band [5,6,11,12,[15][16][17][18][19][20], the size of the antenna in [5,6,11,16,17] is still relatively large. Recently, UWB MIMO antennas with notch-band characteristic have been introduced [21,22].…”

Abstract-In this paper, a compact multiple-input-multiple-output (MIMO) antenna is proposed for ultra wideband (UWB) communication. The UWB MIMO antenna consists of two identical monopole antenna elements with a comb-line structure on the ground plane to improve impedance matching and enhance isolation. Simulation and measurement have been analysed in terms of reflection coefficient, mutual coupling, dispersion diagram, radiation pattern, peak gain, efficiency and envelope correlation coefficient. Results show that the antenna has an impedance bandwidth larger than 3.1-10.6 GHz, mutual coupling between the two ports lower than −25 dB and envelope correlation coefficient less than 0.001 across the UWB band. The proposed antenna has a compact size of 26 × 31 mm 2 . All the measured and calculated results show that the proposed UWB MIMO antenna is a good candidate for UWB MIMO systems.

Abstract-This paper presents a 4x4 MIMO filtenna aimed for use with UWB applications. The MIMO filtenna is simulated, fabricated and measured. Obtained simulation and measurement results agree well with each other and have been presented to validate the accuracy of the proposed structure. Measured passband is 2.96-11.56 GHz, with dual bandnotch at 3.5 GHz (S 11 = -1.25 dB) and 6.05 GHz (S 11 = -2.4 dB). Measured isolation is more than 20 dB between all individual elements of the MIMO filtenna. The behaviour of current within the filtenna at the bandnotch frequencies has been shown. Elements of the filtenna exhibit bi-directional radiation patterns in the E-plane and omnidirectional patterns in the H-plane. The gain and efficiency have also been presented; with the average values being 5.3 dBi and 90% respectively. The Envelope Correlation Coefficient has been calculated from both simulations and measurements; with the measured values being below 0.001 for the passband.
