%0 Journal Article %T Corrugated Substrate Integrated Waveguide (SIW) Antipodal Linearly Tapered Slot Antenna Array FED by Quasi-Triangular Power Divider %A Tarek Djerafi %A Ke Wu %J PIER C %D 2012 %I EMW Publishing %R 10.2528/PIERC11091912 %X In this paper, a new configuration of Tapered Slot Antenna (TSA) with improved radiation pattern is proposed and studied. This antenna is designed in the form of a substrate integrated waveguide (SIW) array with respect to side lobe level constraints. For side lobe reduction, a simple quasi-triangular distribution is proposed and is accomplished uniquely by means of 3 dB power dividers. A 12-way series feed network with T-junction is designed and demonstrated. Radiation features of the antenna array are discussed to illustrate the accomplishment of a low side lobe level (-19 dB) of the array. The proposed antenna demonstrates the ability of the SIW technology to achieve a very low side lobe in a simple, compact and planar structure. %U http://www.jpier.org/pierc/pier.php?paper=11091912
