In this paper, a novel L network (LN) is presented, which is composed of a frequency-selected section (FSS) and a middle stub (MS). Based on the proposed LN, a tri-band T-junction power divider (TTPD) with impedance transformation and independent power division ratios is designed. Moreover, the closed-form design theory of the TTPD is derived based on the transmission line theory and circuit theory. Finally, a microstrip prototype of the TTPD is simulated, fabricated, and measured. The design is for three arbitrarily chosen frequencies, 1 GHz, 1.6 GHz, and 2.35 GHz with the independent power division ratios of 0.5, 0.7, and 0.9. The measured results show that the fabricated prototype is consistent with the simulation, which demonstrates the effectiveness of this proposed design.
本文提出了一种新型的L网络（LN），它由一个频率选择部分（FSS）和一个中间短截线（MS）组成。基于所提出的L网络，设计了一种具有阻抗变换和独立功率分配比的三频段T型结功率分配器（TTPD）。此外，基于传输线理论和电路理论推导了TTPD的闭式设计理论。最后，对TTPD的微带原型进行了仿真、制作和测量。该设计针对三个任意选择的频率，即1GHz、1.6GHz和2.35GHz，独立功率分配比分别为0.5、0.7和0.9。测量结果表明，制作的原型与仿真结果一致，证明了该设计的有效性。
