In this work, a novel multiband, four‐element, meandered‐line reconfigurable planar F‐shaped multiple‐input‐multiple‐output antenna is presented. The proposed design includes chassis mode reconfigurability option as well. A combination of PIN and varactor diodes is used to achieve the frequency tuning over a wide‐band. The proposed design covers several well‐known frequency bands between 0.7 and 3 GHz. The design is compact and realized on a single commercial substrate board with dimensions 65 × 120 × 1.56 mm 3 that can be used in small wireless handheld devices for cognitive radio applications. © 2015 Wiley Periodicals, Inc.
