Abstract
The development of receiving dual-band or multiband antennas has witnessed explosive growth driven by their usefulness in the satellite navigation systems in recent years.Two kinds of dual-band circularly polarized(CP)antennas working at BD-B3(1.268 GHz)and GPS-L1(1.590 GHz)fre-quencies are designed.One kind of the methods is realized by means of unit form.The other is array form with five units.The array center unit operates at the higher frequency band,and the surrounding four u-nits work in the lower freqnency band.Two patches are stacked longitudinally and high dielectric constant substrates are used,while keeping the antenna low profile and small size to meet the requirement of satel-lite navigation systems.The use of Wilkinson power dividers effectively broadens the bandwidth of the an-tenna and the results show that the proposed structure is an excellent candidate for CP antennas.关键词
