| Abstract: | Substrate integrated waveguide （SIW） is a new type of waveguide structure, which has advantages such as low insertion loss, high Q value and easy to process and design, it has good application potential in the fields of radar, communication, navigation etc. A Ku-band multi-beam slot array antenna based on Butler matrix feed network is designed by using of SIW technology ; simulation results show that synchronous four-beam in elevation which can cover ＋ 45 ° （in elevation） are achieved, and excellent pattern and voltage standing wave ratio （VSWR） performance are obtained. Moreover by using of integrated design, weight and dimensions of the array antenna are both decreased significantly; it has high practicability in engineering application. |
