초록

본 논문에서는 강유전체 기반, 마이크로스트립 라인을 이용하여 13~170Hz에 걸친 넓은 주파수 범위에서 삽입 손실이 2dB 이하, 반사 손실이 10dB 이상인 4-coupled 가변 위상 천이기를 제안한다 특히, 15GHz에서 위상 천이 편이(DPS)는 0V를 인가하였을 때 $89{\circ}$ 이었고, 인가 전압을 150V로 증가시켰을 때 $115{\circ}$ 이었다. 그러므로 위상 천이 편이의 가변성은 $26{\circ}$에 달한다.

In this paper, we propose a 4-coupled ferroelectric-based meander-type microstrip-line tunable phase shifter which has less than 2dB of insertion loss (IL) and larger than 10dB of return loss (RL)over 13~170Hz .Particularly at 15GHz, the differential phase shift (DPS) is observed to be $89{\circ}$ at zero bias and it increases up to $115{\circ}$ when 150V is applied. This indicates a DPS tunability of $26{\circ}$.
