Ultra wideband square slot antenna

In the example above, the antenna is fed with a simple coax feed accross the slot. One of the problems with this is that the optimum distance of the feed to the short end of the slot changes with frequency. Ultra-wideband antipodal slot antenna with improved radiation ...

Ultra-Wideband Microstrip Antenna and Design - A Review Microstrip antenna has a disadvantage of narrow bandwidth whereas UWB antenna has frequency band of 3.1-10.6 GHz. Antenna bandwidth can be increased by using different technique such as embedding slot, parasitic stub, bandstop transmission line, and hybrid techniques. Ultra-Wideband Antenna and Design - InTech - Open Ultra-Wideband Antenna and Design 133 Figure 10. Various wideband techniques for planar square monopole antennas [15-19]. 3.2. UWB printed monopoles The aforementioned planar monopole antennas achieve an ultra-wideband performance based on various techniques, but they all need a perpendicular ground plane, resulting in Implementation of rectangular slit-inserted ultra-wideband ... In this paper, a tapered slot antenna capable of ultra-wideband communication was designed. In the proposed antenna, rectangular slits were inserted to enhance the bandwidth and reduce the area of the antenna. The rectangular slit-inserted tapered slot antenna operated at a bandwidth of 8.45 GHz ...

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. 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.
