Enhancement of return loss and gain using 10mm air-cut technique for integrated SIW filtenna / Nurul Syafeeqa Ishak

This paper presents a design of integrated substrate integrated waveguide (SIW) filter and microstrip antenna using multilayer approach at the nearest frequency of 2.38GHz. The design has been using Roger RT/Duroid 5880 with permittivity of £r =2.2 and a thickness of 0.787mm as a substrate. The desi...
