A wideband siw-to-waveguide transition at w-band - IEEE Xplore
Webb1 jan. 2024 · This paper presents a design of a high gain cavity-backed circular patch antenna for X-band applications. By using substrate integrated waveguide (SIW) based cavity and feeding mechanism of a microstrip-SIW-transition based on a taper. The proposed antenna is investigated in terms of antenna performances including reflection … WebbMe considero una persona curiosa y creativa, apasionada por el fenómeno físico, químico y/o matemático, la aplicación real y el por qué detrás de las cosas, y siempre encantado de afrontar nuevos retos. Siempre intento estar estimulado mentalmente. A lo largo de mi trayectoria académica, he adquirido diferentes conocimientos en el ámbito de las … Webbsingle-layer SIW with tapered microstrip transition feed is as shown in Fig. 3. The SIW is implemented on a commercially available low cost FR4 substrate with r=4.3 and tan δ=0.02 and the substrate height is 0.8mm. The desired cutoff frequency for the dominant mode is fc= 8GHz.
