Novel Dual-Band Design of Planar Dipole Array for 4G LTEWiMAX Access Points

الملخص EN

A novel planar 1×4 dipole array with dual-band operation for LTE/WiMAX access points is proposed.

The impedance bandwidths, determined from VSWR≦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.
