WIDE BEAM TAPERED SLOT ANTENNA FOR WIDE ANGLE SCANNING PHASED ARRAY ANTENNA A. Kedar and K. S. Beenamole Electronics & Radar Development Establishment (LRDE) C V Raman Nagar, Bangalore 560093, India Abstract|Design and development of a low proflle, compact, wide beam and wide band printed double layered exponentially tapered slot Investigation on SIW Slot Antenna Array with Beam Scanning ... The S11 and radiation of the slot array antenna unit are shown in Figure 3. The −10 dB impedance bandwidth is from 13.4 to 15.2 GHz (relative bandwidth is 12%), with a gain of 7.86 dB at 14 GHz. The beam width is 140° in the E-plane, which indicates that it can be used as a unit antenna for a wide-angle coverage phased array. Antenna Theory - Slot - Tutorials Point

In this paper, a tapered slot antenna is designed and proposed. The antenna has a 3 dB beam width, high gain, and directive characteristics, which are appropriate for reducing the area of the antenna and for location recognition. The bandwidth was improved by inserting rectangular slits in the radiator of the antenna.
Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. Characteristics of Double Exponentially Tapered Slot ... pattern. A Double Exponentially Tapered Slot Antenna (DETSA), a variation of the Vivaldi Antenna, designed for Ultra Wide Band (UWB) applications conformed over a gently rounded foam shape in the longihldial direction is described in [6]. It was shown that the main beam is skewed towards the direction of curvature.
The rectangular slit-inserted tapered slot antenna operated at a bandwidth of 8.45 GHz, and the bandwidth improved upon the basic tapered slot antenna by 4.72 GHz. The radiation pattern of the antenna was suitable for location recognition in a certain direction owing to an appropriate 3 dB beam width. Nonplanar Linearly Tapered Slot Antenna With Balanced ... the antenna. INTRODUCTION Linearly tapered slot antennas (LTSAs) have many salient features such as narrow beam width, high element gain, wide bandwidth and small transverse spacing between elements in an array. These features make them attractive in satellite communication antennas involving beam shaping and switching (ref. 1). Design And Analysis Of Compact U Slot Microstrip Patch ...
