Introduction

Yong-Heui Cho is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of antenna measurement technologies. With a total of 4 patents to his name, his work has advanced the understanding and capabilities of antenna radiation pattern measurement.

Latest Patents

Cho's latest patents include an "Apparatus and method for measuring antenna radiation patterns." This innovative device measures the radiation pattern of an Antenna Under Test (AUT) using a source antenna. The system comprises a control unit, an analysis unit, and a measurement unit. The control unit manages the operation of both the source antenna and the AUT. The analysis unit captures the electric field value from a radio frequency (RF) signal transmitted between the antennas. The measurement unit then utilizes this electric field value to determine the radiation pattern of the AUT.

Another notable patent is the "Camera based positioner for near-field measurement and method therefor." This invention provides a camera-based positioner (CBP) that automatically aligns a measurement probe and the AUT for near-field antenna measurement. The alignment is achieved by recognizing the position and rotation angle of the AUT through images captured by laser beams emitted from multiple laser sources.
