Design of ultra wideband trapezoidal shape slot antenna with ... A number of slot antenna designs for CP have appeared in the published literature. In , a halberd shaped tuning stub was used to excite a square slot and a CP band of 1575 MHz (3.81%) was achieved. A stair shaped slot antenna was proposed in that gave a 31.2% axial Ultra‐wideband square‐slot antenna | Request PDF A simple square-slot antenna capable of providing a very wide impedance bandwidth of larger than 9 GHz is presented. The ultra-wideband operation for the proposed antenna is realized by using a Band‐notched ultra‐wideband square slot antenna - DeepDyve An ultra‐wideband (UWB) square slot antenna with a band‐notched characteristic is presented. The proposed antenna has a simple configuration and is easy to construct. The ultra‐wideband operation is realized by loading an offset rectangular stub at the end of

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. Printed Wide Slot Ultra-Wideband Antenna - InTech - Open nular-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 pro‐ posed in [17]. By properly choosing the location and size of the tuning stub, the proposed antenna achieved a bandwidth of 60% with an overall dimension of 72 mm × 72 mm. Maximizing Gain of a Compact UWB Tapered Slot Antenna
Abstract: This communication presents the design of an ultra-wideband antipodal tapered slot antenna (ATSA) with frequency notch characteristics. Subwavelength resonators in the form of square split-ring resonators are placed on the aperture as well as on the feed section of the ATSA to invoke the frequency notches.
