Abstract
By loading rectangular slots at each edge of the rectangular patch for generating perturbation, the circular polarization was achieved in 2.45 GHz and 5.04 GHz bands, respectively.Also, by adjusting the length of each rectangular slot, impedance and width was matched with the3-dB axial ratio band width.The size of antenna , which is feed by coaxial, is 0.218λ0 ×0.211λ0×0.013λ0 (λ0 is the wavelength at 2.45 GHz in free space).Measured results show that the circular polarization operating bandwidth of the antenna are 1.26% (2.445~2.476 GHz), 0.92% (5.013~5.059 GHz), and the peak gain in two frequency bands are 1.25 dBi and 1.32 dBi, respectively.The measured results are in close agreement with the simulation results.关键词
