Abstract

To satisfy the increasing requirements of wireless communication, a compact dual band MIMO antenna is presented in this paper. The presented antenna consists of two symmetric radiating elements operating at both 3.5 and 4.5 GHz bands. To enhance the isolation between the two radiating elements, an I-shaped decoupling structure is introduced. The measured −10 dB reflection coefficients frequency bands are 3.3–3.8 and 4.3–5.8 GHz. The measured isolation S21 between the two radiating elements are better than 15 and 17 dB at the lower and higher frequency band, respectively. The overall dimension of the proposed antenna is 50 × 22 × 1.59 mm3. The measured result indicates that the proposed antenna can be a good candidate for 5 G/WLAN wireless communication.
