ABSTRACT This article presents a tri‐band multiple‐input–multiple‐output (MIMO) mobile antenna for WWAN and LTE applications. The tri‐band antenna element consists of a planar inverted‐F antenna (PIFA) which is coupled‐fed by an L‐shaped driven strip monopole. Long parallel folded strip (PFS) printed adjacent to the upper edge of PIFA is used to generate an additional mode in the lower band, making the antenna capable of covering the whole GSM850 and GSM900 bands. Two n ‐shaped strips are placed between the antenna elements to improve port isolation. The proposed antenna exhibits triple bands including the lower band of 0.81–0.97 GHz, the middle band of 1.36–2.80 GHz, and the upper band of 3.40–3.75 GHz for WWAN and LTE applications. Detailed geometry and working mechanisms of the antenna are presented. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1446–1450, 2017
