Title: Martin Obermaier: Innovator in Antenna Measurement Technologies

Introduction

Martin Obermaier is a distinguished inventor based in Dresden, Germany. He has made significant contributions to the field of antenna measurement technologies, holding a total of three patents. His work focuses on enhancing the accuracy and efficiency of antenna testing methods.

Latest Patents

Obermaier's latest patents include innovative systems and methods for testing an antenna-under-test (AUT). One of his notable inventions involves combining signals transmitted from multiple probe antennas in over-the-air antenna measurements. This system utilizes a multi-probe antenna array transmitter that is moved to various positions within a scan area. At each position, each probe antenna element transmits a near-field (NF) over-the-air (OTA) signal to the AUT. An alignment procedure is performed to ensure accurate transmission locations, and correction factors are determined to address amplitude and phase discrepancies. The corrected signals are then combined to obtain average signals, which are used to determine a far-field (FF) reception pattern for the AUT.

Another significant patent by Obermaier focuses on combining signals received from multiple probe antennas in over-the-air antenna measurements. In this system, a multi-probe antenna array receiver is also moved to various positions within a scan area. Each probe antenna element receives a near-field (NF) OTA signal from the AUT, and similar alignment and correction procedures are applied. The resulting average signals are used to determine a far-field (FF) transmission pattern for the AUT.
