A 2x1 Dual-Band MIMO Antenna using Complementary Split Ring Resonator for Wireless Applications

Abstract

This paper presents a compact 2x1 dual-band MIMO antenna with complementary split ring resonator proposed for wireless applications resonate at two different frequencies 2.58GHz and 5.71GHz. Radiating elements are linearly polarized. The proposed MIMO covers 2.30-2.84GHz and 5.54-5.82GHz frequency bands with low return loss especially at lower band 40.20dBi. The antenna is designed by introducing Complementary Split Ring Resonator (CSRR) between radiating elements and inverted L-slot on partial ground. The whole layout is designed over alow cost FR4 substratehaving dielectric constant ?r = 4.3 with loss tangent 0.02. The size of proposed design is reduced to 29.16x34.39mm2.The gain at the 2.58 GHz resonant frequency is 1.16dBi and at 5.71GHz resonant frequency gain is 1.01dBi. The simulated result shows the Envelope Correlation Coefficient (ECC) of 0.01 and more than 10 dB of in –band isolation.Theproposed designed MIMO include the LTE and WLAN Band.
