Performance of a Crossed Exponentially Tapered Slot …

A dual-band dual-polarized nested vivaldi slot array with ... exponentially-tapered Vivaldi slot have been demonstrated to exhibit broad-band operation in both return loss and radiation patterns [6]. In an array of such elements, bandwidth perfor-Fig. 4. Simulated versus measured return loss of theoptimized-taper = 400 small antipodal Vivaldi antenna with the microstrip to printed-twinline balun. Vivaldi antenna - Wikipedia A Vivaldi antenna or Vivaldi aerial or tapered slot antenna is a co-planar broadband-antenna, which can be made from a solid piece of sheet metal, a printed circuit board, or from a dielectric plate metalized on one or both sides. 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 ...

I. INTRODUCTION apered Slot Antenna (TSA) Arrays are of large interest for T Ultra-Wide Band applications from the time they were introduced by Lewis et1A illustrates an exponentially tapered aperture fed by a microstrip line printed on a relatively expensive and potentially lossy substrate.

antenna was an exponentially tapered slot, the Vi-valdi Antenna [3], and a double exponentially tapered slot an-tenna (DETSA) has been introducedThe E-plane cross-polarization level is nearly constantwith frequency, but it increases by approximately 15 dB as theradius of curvature decreases. A Ka-band Planar Printed Antipodal Linearly-tapered Slot… The broadband and high gain nature of tapered slot antennas (TSA) have been reported for years. Due to its coplanar structure, the TSA is easily integratedIn addition, analysis methods presented were focused on coplanar structures, especially on TSAs with an exponentially tapered slot profile.
