Dual band MIMO antenna composed of inverted L elements printed on dielectric substrate

The dual band MIMO antenna composed of inverted L antenna is proposed and numerically analyzed. The design frequency is 2.4 GHz to 2.5 GHz, 5.15 GHz to 5.35 GHz. Inverted L antenna is formed by the coplanar waveguide. The parasitic planar rectangular loop is placed above the of inverted L antenna. When the size of conducting plane is 51 mm by 48 mm, the S11 less than -10 dB is satisfied from 2.4 GHz to 2.5 GHz, and 5.15 GHz to 5.35 GHz. The distance between two antennas is 35 mm. The S21 less than -20 dB and the correlation coefficient less than 0.002 are satisfied at these two frequency bands. In the numerical analysis, the electromagnetic simulator WIPL-D based on the Method of Moments is used.
