Abstract A highly compact 2 × 2 (four element) and 2 × 4 (eight element) multiple‐input‐multiple‐output (MIMO) antenna systems are designed for the IEEE 802.11ac standard. The antennas operate in the 5‐GHz band with a minimum effective bandwidth of 80 MHz. The elements of the MIMO antenna system are patch antennas loaded with complementary split‐ring resonators. A minimum isolation of 10.5 dB and maximum gain of −0.8 dBi are measured. Total size of the MIMO antenna systems is 50 × 100 × 0.8 mm 3 . © 2013 Wiley Periodicals, Inc.
