| Description: |
A 2x1 wearable multiple-input-multiple-output (MIMO) antenna with line patch as mutual coupling suppression is presented. The proposed MIMO antenna is based on a simple rectangular structure that works at 2.45 GHz frequency. The patches are designed using ShieldIt textiles and are placed to a very closed (0.1λ) gap. The results show that the suppression in the mutual coupling of 5 dB (from -20 dB to -25dB), reduced by 25% after the line patch is inserted in between patches. On a positive note, an improvement in the antenna gain, from 4.4 dB to 4.7dB is achieved. On top of that, the performance of the reflection coefficient (S 11 ) and the antenna impedance bandwidth is preserved. Important diversity performance parameter for MIMO antenna such as ECC, diversity gain and MEG results are found to be in an acceptable limit |
