Analytical Study of Corrugated Linearly Tapered Slot Antenna

Abstract


The tapered slot antenna, such as Vivaldi, has been
widely used due to its ultra-wideband, simple feed structure, and easy fabrication. However, the obtained radiation patterns show that conventional tapered slot antenna suffers from poor directivity in the lower part of band. To overcome this shortfall, corrugations were added on its sides. By comparing performances of the conventional and corrugated TSA it was demonstrated that by choosing a suitable corrugation pattern the directivity and beam efficiency can be improved. Our aim is to propose a wide band, higher gain Corrugated
linearly tapered slot antenna (CLTSA) with relatively low
cross-polarization levels and also to investigate how different patterns of corrugations will affect the radiation characteristic of linearly tapered slot antenna.
