摘要： The present invention relates to a dual-band microstrip (20)-slotline (31) transition circuit which operates in two frequency bands. A first filtering circuit (32) is connected between a first microstrip line part and a first input/output port P10, wherein a first circuit and the microstrip line part are used to receive the frequencies from a first frequency band and block the frequencies of a second frequency band. A second filtering circuit (33) is connected between a second microstrip line part and a second input/output port P20, wherein a second circuit and the mircrostrip line part are used to receive the frequencies from the second frequency band and block the frequencies of the first frequency band. The size of the slotline is determined to provide almost the same impedance as the impedance of an open circuit in the coupling zone between the microstrip line and the slotline.

摘要： A power divider including low pass filter based on RFID (Radio Frequency Identification) system is provided to implement the micro system by reducing the length of the transmission line by 1/2. The signal is input to an input port (P1). The inputted signal moves through an input terminal transmission line (12c). The low pass filters (12a, 12b) are connected to the input terminal transmission line. The low pass filter is arranged in both side of the input terminal transmission line symmetrically. The low pass filter removes the harmonic included within the signal passing through the input terminal transmission channel. The signal of the low pass filter is outputted through the output terminal transmission line (12e) to the output port (P2, P3). The isolation resistor (12d) is arranged between the low pass filters in the output terminal transmission line. The isolation resistor matches the impedance between the input port and the output port. The low pass filter comprises the feed line, the parallel coupled line and an open stud. The feed Line is connected to the input terminal transmission line and the output terminal transmission line. The parallel coupled line is connected to the feed line. The mutual inductance is generated between parallel to two lines. The feed line, the parallel coupled line and the open stud are the microstrip line. The feed line, the parallel coupled line and the open stud are formed in top of the one substrate.

본 발명의 구성에 따르면, 기판상의 소정점(o)을 중심으로 하여 방사상으로 연장되는 제 1∼제 4 선로(L1∼L4)를 구비하고, L1∼L4의 선로상의 o점으로부터 거리(r1)만큼 떨어진 점을 p11∼p14, 마찬가지로 거리(r2)만큼 떨어진 점을 p21∼P24로 하며, 인접하는 점간을 연결하는 접속선(C1∼C4)을 곡선, 직선 또는 둔각의 절선(折線)으로 하고, 이 접속선과 선로 가장자리단부와의 교차각을 둔각으로 하며, 이들 접속선(C1∼C4)과 선로(L1∼L4)로 둘러싸인 영역을 도체 패턴(R1∼R4)으로 한다. 그리고, r1, r2를 다른 값으로 하여, 복수의 공진 모드의 축퇴 관계를 해제한다.
