This article proposes a novel planar dipole array antenna with dual-band operation for long-term evolution (LTE)/worldwide interoperability for microwave access (WiMAX) communication systems. This array antenna is comprised of four dipole antennas to obtain high gain with the array antenna size of only 32 Â 246 mm 2 . The impedance bandwidths, determined from VSWR 2.0, can reach about 555/765 MHz (21.3/21.9%) for the 2.6/3.5 GHz operating bands, respectively, which is covering the required bandwidth for LTE (2.5-2.7 GHz) and WiMAX (3.3-3.7 GHz) system. This proposed dual-band dipole array also provides maximum peak antenna gains and efficiencies of 6.9/6.5 dBi and 85/79% across 2.6/3.5 GHz bands, respectively, with good omnidirectional radiation pattern in XY-plane.

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.

This article proposes a planar dual-band slot array antenna with high-gain operation for LTE / WiMAX access point. The impedance bandwidths, 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.
