PIFA-BASED 16 x 20 LARGE MIMO CUBE ANTENNA

摘要

A wideband dual polarized planar inverted F antenna-based 16 x 20 multi-input multi-output (MIMO) antenna cube with radome is designed and developed with an aim to achieve high data rate (>1 Gbps) wireless link in an urban street grid scenario. Developed antenna is mechanically stable and has a volume of 1.8 lambda o(3). All the elements have a wide impedance bandwidth from 2.4 to 2.8 GHz (VSWR < 1.6), low mutual coupling (<-15 dB) with almost hemispherical coverage (120 degrees beam width) and peak gain of 3 dBi. MATLAB codes were generated to calculate mean effective gain (MEG), envelop correlation and channel capacity using simulated and measured values of antenna parameter. For urban street grid line of sight case, expected channel capacity of our 16 x 20 MIMO cube antenna is 80 b/s/Hz at 30-dB SNR, with MEG (0 dB) and envelop correlation coefficient less than 0.7.
