An eight ports multiple-input multiple-output (MIMO) patch antenna array operating at 2.4 GHz and 3.5 GHz band is presented in this paper, which can be used for the Long Term Evolution (LTE), Microwave Access (WiMAX) and the low frequency band of Wireless Fidelity (WiFi). The presented antenna is fabricated on a F4B-2 substrate (ɛr = 2.65, tan δ = 0.002), it consists of four coplanar E-shaped patches which are orthogonal to each other. Two feed ports are respectively located at two adjacent sides of each patch. Double symmetrical slots are etched out in each patch to improve the antenna bandwidth, a 46 mm × 33 mm metal parasitic patch is placed above each patch to improve the gain. The maximum gain of the proposed antenna array is more than 8 dB at 2.4 GHz band and 9 dB at 3.5 GHz band respectively.
