A dual-band Multiple-Input-Multiple-Output (MIMO) antenna with two ports for Long-Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WIMAX) applications is presented. The antenna is derived from a non-radiation equivalent circuit with enough isolation achieved by meeting the decoupling requirement $\mathbf{S}_{21}=0$. The circuit consisted of two pairs of symmetrical open-ended stubs connected by a transmission line realizes good intrinsic port isolation without employing complicated decoupling mechanisms. Ultimately, desired radiation can be obtained through impedance matching while port isolation unaffected almost. The antenna operates at 1.9-2.2 GHz and at 3.4-3.6 GHz and the measured minimum value of isolation between two ports is more than 20 dB in both operating frequencies.

Abstract
A dual-band Multiple-Input-Multiple-Output (MIMO) antenna with two ports for Long-Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WIMAX) applications is presented. The antenna is derived from a non-radiation equivalent circuit with enough isolation achieved by meeting the decoupling requirement $\mathbf{S}_{21}=0$. The circuit consisted of two pairs of symmetrical open-ended stubs connected by a transmission line realizes good intrinsic port isolation without employing complicated decoupling mechanisms. Ultimately, desired radiation can be obtained through impedance matching while port isolation unaffected almost. The antenna operates at 1.9-2.2 GHz and at 3.4-3.6 GHz and the measured minimum value of isolation between two ports is more than 20 dB in both operating frequencies.
