Title:
DESIGN METHOD AND CIRCUIT FOR DUAL-BAND NON-UNIFORM TRANSMISSION LINE IMPEDANCE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2018/076519
Kind Code:
A1
Abstract:
A circuit and a design method for a dual-band non-uniform transmission line impedance converter. The method optimizes the structural size of an impedance converter by means of a mathematical optimization model, changes the corresponding transmission line of the impedance converter into a non-uniform transmission line, and causes the width of the transmission line to continuously change in a longitudinal direction, thereby realizing a smooth transmission of electromagnetic wave signals on the transmission line. The circuit comprises a T-type impedance converter, an n-type impedance converter and an H-type impedance converter. The impedance converter implemented by means of the design method has a small reflection coefficient, large harmonic suppression, small insertion loss, a large bandwidth, a physical size smaller than that of a conventional uniform transmission line impedance converter, and a more flexible design. Moreover, the impedance converter can be used for matching any plural number of terminal impedances without any centralized reactance element, and consumes few resources and is widely applicable.
