우수한 차단 특성을 갖는 ITS용 SIR 대역 통과 여파기
A Stepped Impedance Resonator Bandpass Filter with Superior Cut-off Response for ITS Application
Abstract
In this paper, a bandpass filter with excellent cut off characteristic due to transmission zero using bypass coupling capacitor and with superior harmonic characteristic by interdigital capacitor is suggested. The measurement results for SIR bandpass filter with bypass coupling capacitor and interdigital capacitor show that the insertion loss is less than 1.9 dB and the return loss is better than 15.4 dB with 4.2 % bandwidth at the center frequency of 5.78 GHz.
