Abstract

The invention provides a flexible power divider, which mainly solves a problem that an existing power divider cannot achieve flexibility. The flexible power divider comprises a front half part (5) anda rear half part (6), wherein the two parts are symmetrical relative to a center line (7); each part comprises a transmission line layer (1) and a flexible dielectric layer (2), wherein the transmission line layer is etched on the upper surface of the dielectric layer, is reversed-V-shaped and is provided with an input port (8) and two output ports (9 and 10), and each port is provided with two petal-shaped films (4), wherein the transmission line layer adopts an artificial surface plasmon transmission line, so that the dependence of electromagnetic energy transmission on a metal floor is avoided, and the flexibility of the power divider is achieved; a high-resistance conductive film (3) is printed on the upper surface of the dielectric layer for improving the isolation degree between thefirst output port and the second output port in order to achieve flexibility. According to the flexible power divider, the bendability of the power divider is realized on the premise of ensuring thehigh isolation degree of the power divider, and the flexible power divider can be used in a radio frequency microwave circuit system.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a flexible power splitter, which can be used for power distribution or synthesis with high isolation requirements and high device flexibility requirements, and is suitable for radio frequency microwave circuit systems. Background technique [0002] The full name of the power divider is a power divider, which is a multi-port passive microwave network that divides the power of one input signal into two or more equal or unequal power outputs. On the contrary, it can also perform power synthesis on multiple signals. . The common types of power splitters mainly include waveguide power splitters, coaxial cavity power splitters, microstrip line power splitters and stripline power splitters. in: [0003] The power capacity of the microstrip power splitter is small, and the phase consistency is not ideal. In the case of multiple nodes, the insertion loss of the power spli...
