A novel planar 1 × 4 dipole array with dual-band operation for LTE/WiMAX access points is proposed. The impedance bandwidths, determined from V S W R 2 . 0 , can reach about 525/747 MHz (20.2/21.3%) for the 2.6/3.5 GHz operating bands, respectively, which are 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 7.3/7.5 dBi and 89/75% across 2.6/3.5 GHz bands, respectively, with good omnidirectional radiation pattern in XY-plane.
