Divided Two-arms Spiral Slot Antenna fed by Coplanar Waveguide Using the Different Magnetic Phase Different

摘要：

In this paper, we proposed a divided two-arms spiral slot antenna fed by coplanar waveguide using the magnetic flow at slots. This antenna has characteristics of which one is to short-circuit at the end of the slot and another is to turn spirals separately. To reduce the offset of the magnetic flow, two spiral slots are fed by the different phase of π(180°). Because we proposed the printed two-arms spiral slot antenna without a balun circuit, the antenna size become smaller substantially. And frequency characteristics are studied by using the various design parameters. The bandwidth of the fabricated antenna is 2.7 GHz～12 GHz below the return loss of -10 dB.
