This article proposes a novel planar dual‐band slot array antenna with high‐gain operation for Long Term Evolution (LTE)/Worldwide Interoperability for Microwave Access (WiMAX) point. The impedance bandwidth, determined from VSWR ≤ 2.0, can reach about 18.3/14.6% (475/510 MHz) for the 2.6/3.5 GHz operating bands, respectively, which is covering the bandwidth specification for LTE (2.5–2.7 GHz) and WiMAX (3.3–3.7 GHz) system. The proposed slot array antenna also provides maximum peak antenna gains and efficiencies of 13.9/14.1 dBi and 86.5/73.5% across 2.6/3.5 GHz bands, respectively. © 2012 Wiley Periodicals, Inc.
