A reconfigurable dual-band monopole array with high isolation for WLAN MIMO application is proposed. This antenna array contains two C-shaped monopoles with a shorting line, on which two RF switches were integrated, connecting the two antenna elements that are separated by a distance of 0.09λ2.4 GHz. High isolation at 2.4 or 5.2 GHz bands can be achieved by changing the states of the RF switches. Experiment results indicate that the proposed antenna array has a −10 dB bandwidth that covers the required frequencies for dual-band WLAN applications with an isolation higher than 20 dB over the lower operation bands when the RF switches are ‘ON’, and an isolation higher than 17 dB at the higher operation band when the switches are ‘OFF’.
