Abstract
A novel design of four-port MIMO antenna with backed co-located dual cavities is presented. The proposed MIMO antenna can operate in dual band and dual polarization for WLAN applications. By means of the backed co-located dual cavities, the proposed antenna can generate unidirectional radiation patterns in the 2.4GHz and 5.5GHz bands. Using two orthogonal feedings, the antenna can achieve dual polarized radiation patterns in both bands. With the compact dual co-located cavities structure, the proposed MIMO antenna shows good port-to-port isolation better than 17.5 dB in both operation bands. The radiation patterns also shows decent polarization isolation greater than 15dB. The proposed MIMO antenna is very compact as it integrates four-port antennas in the same radiating area. The proposed dual-band and dual-polarized antenna with unidirectional radiation patterns is suitable for smart antenna system in advanced MIMO wireless communication applications.
