Abstract

A single-arm rectangular spiral antenna with a tilted beam working in 1.9GHz-2.2GHz frequency band is presented in this paper. The spiral is printed on a finite-size dielectric substrate backed by a finite-size conducting plane. Both the substrate and conducting planes are square with a side length L of less than 0.6λ_o (λ_o: wavelength in free space). The radiation pattern is dependent on the outermost arm peripheral length C. The spiral whose peripheral length is within 2λ_g <; C <; 3λ_g (λ_g: the guided wavelength of the current) radiates a tilted beam of circular polarization. The simulated results for the radiation pattern, gain, and VSWR are presented.
