Abstract
Official abstract text for this publication.
A series tee splitter comprises a primary electromagnetic transmission line and a secondary electromagnetic transmission line that is placed in a series path with the primary electromagnetic transmission line, wherein a load is attached to the end of the secondary electromagnetic transmission line and a network analyzer is connected to opposite ends of the primary electromagnetic transmission line to measure a load impedance. This configuration increases the high impedance measurement limit of the network analyzer normally seen for reflection measurements. The series tee splitter can be electrically small to provide broadband impedance information.
First claim
Opening claim text (preview).
We claim: 1. A series tee splitter, comprising a primary electromagnetic transmission line having a first port and a third port at opposite ends of the primary transmission line, and a secondary electromagnetic transmission line having a second port that is placed in a series path with the primary electromagnetic transmission line, wherein a load is attached to the second port of the secondary electromagnetic transmission line and a network analyzer is connected to the first port and the third port of the primary electromagnetic transmission line to measure an impedance of the load. 2. The series tee splitter of claim 1 , wherein the primary electromagnetic transmission line comprises a microstrip line structure and the secondary electromagnetic transmission line comprises a parallel conductor structure built on a T-shaped substrate with the secondary electromagnetic transmission line on the stem of the T-shaped substrate. 3. The series tee splitter of claim 1 , wherein the primary and secondary electromagnetic transmission lines have a 50-Ω characteristic impedance. 4. The series tee splitter of claim 2 , wherein the substrate comprises a low permittivity material. 5. The series tee splitter of claim 4 , wherein the substrate has a relative permittivity of less than 10. 6. The series tee splitter of claim 4 , wherein the low permittivity material comprises acrylonitrile butadiene styrene. 7. The series tee splitter of claim 1 , wherein the network analyzer comprises a vector network analyzer or scalar network analyzer. 8. The series tee splitter of claim 1 , wherein the load impedance can be up to 10 MΩ at a measurement frequency range from 5 Hz to 1 kHz.
