摘要：

A printed dipole antenna with integrated balun is presented. The radiating structure is a two-element dipole with resonances at 900 and 1700 MHz, with the balun providing one extra resonance at each band. By co-designing the radiating element with a Marchand balun modified for dual-band operation, an antenna covering the cellular bands 824-960 and 1710-2170 MHz has been achieved. Measurements on a fabricated antenna on low-cost FR-4 substrate show antenna efficiencies of > 80 and > 70% in the lower and upper band respectively. Despite the use of a dual-element radiator, the radiation pattern that is close to omni-directional H-plane is obtained.
