Compact 4-Port MIMO/Diversity Antenna with Low Correlation for UWB Application
Keyword(s):
Abstract A compact four port multiple-input-multiple-output (MIMO) antenna with polarization diversity for ultrawideband (UWB) application is proposed. The antenna contains four monopoles where each monopole has three concentric rings. Orthogonal arrangement of monopoles of the antenna provides good isolation and polarization diversity. The antenna has compact size of 36×36×1.6 mm3. It operates in the frequency band of 3.2 to 11 GHz where isolation is better than 15 dB. The envelop correlation coefficient (ECC) and diversity gain from S-parameter have been calculated to evaluate MIMO performance of the antenna. In addition to ensure distortion less transmission in UWB group delay is also calculated.
