Dec 18, 2017 ... A linearly polarised antenna with wide beam-width is proposed. This antenna is based on substrate integrated waveguide (SIW) cavity.
Substrate Integrated Waveguide-Fed Tapered Slot Antenna band (18 GHz – 30 GHz) planar linear tapered slot antenna (LTSA) design. From a parametric study involving eight designs, the best compromise LTSA is selected in terms of flattest gain and beam width and most symmetric beam width. The design is antipodal with alumina (εr = 10) substrate and fed with substrate integrated waveguide (SIW). Regular A cavity-backed spiral slot antenna with wide axial ratio
