Bandwidth Enhancement Substrate Integrated Waveguide (SIW) Antenna V-Shape Slot for X Band Application

Substrate Integrated Waveguide (SIW) antenna is a planar form of conventional waveguide antenna. SIW is designed to reduce the size and cost of rectangular waveguide (RWG) and make it easy to be integrated with planar component. There are many studies on SIW antennas have been carried out to improve bandwidth, one of the methods used is designing the slot model of SIW. This study discusses the efforts to increase the bandwidth of the antenna using the SIW dual Slot V shape Antenna facing out towards the center line SIW. The antenna is designed at a frequency of 10 GHz. Based on the simulation results obtained bandwidth of 803 MHz, and the measurement results of 780 MHZ. While the results of the radiation pattern simulation obtained an antenna gain of 8.7dB and the measurement results obtained at 9.52 dB.
