Description
Summary:In this paper, a dual-band Circularly Polarized (CP) compact-sized four elements Multi-Input Multi-Output (MIMO) antenna is presented. The proposed MIMO system consists of four monopoles radiating elements with the same hexagonal shape, and each one has three hexagonal rings. The orthogonal geometry of the proposed antenna is used to provide good isolation and polarization diversity. The dual-band notches are achieved, 3.28–3.77 GHz (13.9%; fc 3.53 GHz) for the lower operating frequency band and 4.02–7.79 GHz (63.84%; fc 5.9 GHz) for a higher operating frequency range. Moreover, the evaluation of MIMO antenna performance shows good diversity performance with Envelop Correlation Coefficient (ECC) less than 0.01, and Diversity Gain (DG) nearly 9.99 dB. The proposed dual-band orthogonal port MIMO antenna is proper for Wi-MAX and WLAN wireless applications.
