Title: Innovations by Andreas Pietsch in Antenna Technology
Introduction
Andreas Pietsch is a notable inventor based in Dulmen, Germany. He has made significant contributions to the field of antenna technology, particularly in the area of fault isolation and inspection methods for radio telephones. With a total of 2 patents to his name, his work has implications for improving communication devices.
Latest Patents
One of his latest patents focuses on the fault isolation of an antenna path for a radio telephone. This method and communications device enable precise location of defective areas in the antenna path, allowing for selective repairs. The process involves coupling a wave with a starting frequency into the antenna path and measuring the amplitude of the standing wave at an angular position. The frequency is then increased until a corresponding amplitude is detected, from which the fault interval can be calculated.
Another patent describes a method and device for inspecting at least one antenna branch, particularly in vehicles. Initially, a power level is fed into the antenna branch, and the reflected power level is sensed. A relationship is formed between the fed-in and reflected power levels to obtain a quality signal that indicates the antenna branch's quality. This method allows for the identification of alternative antenna branches for satisfactory communication when specific branches are damaged.
Career Highlights
Andreas Pietsch is currently employed at Nokia Mobile Phones Limited, where he continues to innovate in the field of telecommunications. His work has contributed to advancements in antenna technology, enhancing the reliability and efficiency of communication devices.
