Planar dual-band dipole array for long-term evolution/worldwide interoperability for microwave access points

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 × 246 mm². 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. © 2012 Wiley Periodicals, Inc.
