摘要: A novel reconfigurable antenna structure allowing polarization rotation is proposed. The a linearly polarized aperture coupled circular patch antenna, with three independent radial feeding lines to rotate the in steps of sixty degrees. desired sense achieved by turning on PIN diode at beginning appropriate line. Measured results show good matching and low cross-polarization levels, agree well theory. proposed architecture can be advantageous for use doubly curved arrays, where possibility align element polarizations directly translates into an increased array gain.
