High Gain Vivaldi Antenna for Radar and Microwave Imaging Applications
An Ultrawideband (UWB) high gain compact Vivaldi antenna with end fire radiation patterns is presented for radar and microwave imaging applications. The antenna is operating for 2.9GHz to more than 11GHz with -10dB impedance bandwidth and is designed on low cost FR4 substrate of thickness 0.8mm. While designing the proposed antenna, initially a compact exponential tapered slot Vivaldi antenna i...
متن کاملDesign of a Compact Tapered Slot Vivaldi Antenna Array for See Through Concrete Wall UWB Applications
An optimized 1×8 Vivaldi antenna array designed for the lower-band UWB (2-4 GHz) through-wall imaging systems has been developed. Tapered slot antennas were utilized as the array elements and optimized to have a compact size. A one to eight wideband Wilkinson power divider was designed and fabricated to compose the feed network for Vivaldi antenna array. Measured results of the manufactured Viv...
متن کاملLinear Tapered Slot Antenna with Defected Side for Improved Gain
Linear tapered slot antennas (LTSAs) have been widely investigated as typical examples of coplanar antennas because the LTSAs offer the advantages of wide impedance bandwidth, high gain, and easy fabrication [1], [2]. However, they have high back lobes in the E-plane [3]. In general, the LTSAs are very sensitive to the thickness and the width of their supporting substrate. It is shown that radi...
