Printed Wide Slot Ultra-Wideband Antenna | IntechOpen By using different tuning techniques or employing different slot shapes such as rectangle, circle, arc-shape, annular-ring, U-shaped [12-16], different slot antennas achieved wideband or ultra-wideband performance. A square slot antenna excited by a CPW-fed widened tuning stub was proposed in . By properly choosing the location and size of the ... Design of ultra wideband trapezoidal shape slot antenna ... A CPW-feed printed slot antenna with circular polarization characteristics is presented in this paper. The basic structure of the antenna is a rectangular slot excited by a 50 Ω CPW line terminated on a trapezoidal shaped tuning stub.Perturbations in the form of circular stubs are applied in the slot to realize circular polarization.
