A WLAN band-notched multiple-input multiple-output (MIMO) ultra-wideband (UWB) antenna is designed and analyzed. The designed MIMO configuration utilizes 0.79 mm thick Rogers RT/duroid 5880 laminate (relative permittivity = 2.2, loss tangent = 0.0009), which is a ceramic-filled Polytetrafluoroethylene (PTFE) composite substrate. The multiple antenna system comprises of two orthogonally placed slotted circular radiators for achieving polarization diversity and high isolation performance. In order to eliminate WLAN band signals, the radiators are carved with split ring resonator (SRR) slots. The modelled diversity antenna having size of 54 × 30 mm2 performs in the frequency range 3-13 GHz, with suppressed band ranging between 4.4 and 5.4 GHz. The isolation amid radiators is significantly higher than 25 dB and the highest gain of 6.5 dB is attained at 8.5 GHz. The proposed MIMO configuration exhibits good diversity performance. Additionally, the antenna performs well according to a number of examined metrics due to the use of low loss substrate with less relative permittivity. The recommended antenna is an appropriate choice for UWB MIMO communication systems, as demonstrated by the simulation outcomes.

摘要

A WLAN band-notched multiple-input multiple-output (MIMO) ultra-wideband (UWB) antenna is designed and analyzed. The designed MIMO configuration utilizes 0.79 mm thick Rogers RT/duroid 5880 laminate (relative permittivity = 2.2, loss tangent = 0.0009), which is a ceramic-filled Polytetrafluoroethylene (PTFE) composite substrate. The multiple antenna system comprises of two orthogonally placed slotted circular radiators for achieving polarization diversity and high isolation performance. In order to eliminate WLAN band signals, the radiators are carved with split ring resonator (SRR) slots. The modelled diversity antenna having size of 54 × 30 mm2 performs in the frequency range 3-13 GHz, with suppressed band ranging between 4.4 and 5.4 GHz. The isolation amid radiators is significantly higher than 25 dB and the highest gain of 6.5 dB is attained at 8.5 GHz. The proposed MIMO configuration exhibits good diversity performance. Additionally, the antenna performs well according to a number of examined metrics due to the use of low loss substrate with less relative permittivity. The recommended antenna is an appropriate choice for UWB MIMO communication systems, as demonstrated by the simulation outcomes.
