기판 집적 도파관 기반 Wilkinson power divider를 적용한 슬롯 배열 안테나 설계

Abstract

In this paper, a Wilkinson power divider based onSIW is designed and applied to an 8×1 SIW slotarray antenna to verify the radiation patternperformance. The proposed Wilkinson power dividerhas a 100 Ω resistor located on a slot, whichoperates with the 𝜆𝑔/4 transformer. The simulatedisolation level is about 32.9 dB, and it is verified thatthe isolation of two outports is secured. Thedesigned Wilkinson power divider is applied to an8×1 SIW slot array antenna, which has a gain of11.20 dBi and a sidelobe level of 17.6 dB
