Abstract
In this paper, a double-band MIMO antenna for wireless applications is proposed. A typical FR4 substrate is used with a thickness is 1.6 mm and size of 80 × 40 mm2, and having two operating bands, one is from 4.7 to 5.4 GHz with the center frequency at 5 GHz and the other is from 5.6 to 6.4 GHz with the center frequency at 6 GHz. The defected ground structure (DGS) is utilized to improve the isolation of the double-band MIMO antenna system. The maximum isolation achieved at both the 5 GHz and 6 GHz center frequencies is 48 dB and 22 dB, respectively. The proposed MIMO antenna is useful for the Wi-Fi application; these bands come under the IEEE standard 802.11 ac with 700 MHz bandwidth. The various diversity performance parameters are also observed. The outcomes of these parameters show that the diversity characteristic performance of this dual-band MIMO antenna design is more effective for the Wi-Fi application.
