In this article, a low‐cost compact multiple‐input multiple‐output array composed of three coplanar waveguide‐fed monopoles printed on flame retardant 4 substrate is presented.The particular feeding mechanism of each single element allows for a wideband behavior, and the specific delta (Δ) shape arrangement of the three radiators leads to a remarkably small footprint. The proposed design is capable of operating in the entire 5–6‐GHz spectrum hence resulting particularly attractive for the IEEE 802.11n 5‐GHz standard. A prototype was fabricated and connected to a Ralink 3 × 3 evaluation board to assess the throughput performance in a typical indoor scenario. The effectiveness of the proposed array is confirmed by experimental results. © 2012 Wiley Periodicals, Inc.
