Abstract:

The optical transparent antenna uses transparent polymer materials, glass and other transparent media materials as the base material, and realizes the non-visualization of antenna radiator and transmission line through the precise circuit metallization process. The optical transparent antenna can be installed on the screen and glasses of smart phones, augmented reality and game devices, as well as other scenes with higher requirements for the concealment of the antenna and the overall industrial design of the product. Due to the need to consider the electromagnetic and optical properties such as radiation pattern, impedance matching, transparency, etc., optical transparent antennas put forward higher requirements on their materials, design, and processing technology. This report has studied the radiator and transmission line design theory, dielectric materials, line processing technology and other aspects of optical transparent antenna, proposed a design method of optical transparent antenna based on metal grid technology, and designed optical transparent antenna working in Sub-6GHz and 28GHz frequency bands respectively, with the transparency of more than 90% and radiation efficiency of more than 60%, basically meeting the operating requirements.

Marc Dirix

Abstract

Using Direct far-field (DFF) for over the air (OTA) testing at sub-6 GHz bands has become the baseline test methodology. With addition of 5G New Radio (NR) rollout and their integration of mm-wave massive multiple input multiple output (Massive MIMO) as well as complex waveforms for communication system testing and primary Figure of Merrit (FoM), the Compact Antenna Test Range (CATR) has been adopted as the preferred test solution. The CATR, initially conceived as a way for testing electrically large antennas at short distances than the usual far-field distance would dictate is now adapted for typically smaller sized measurement setups, both in terms of quiet zone (QZ) size as well as anechoic environment. In these smaller sized measurement setups as well as mm-wave the edge treatment becomes ever more important and wall illumination are significant factors in determining the quality and purity of the collimated pseudo plane-wave. Using modern powerful digital computational simulation techniques in combination with genetic optimization, the edge treatment can be evolved for a specific CATR application as part of the design process for a range of reflector edge treatments. In this talks the optimization of both blended rolled edge (BRE) and serrated edge reflectors is discussed and their respective wall illumination is discussed in detail. Resulting QZ performances are discussed in detail and contrasted.

Abstract:

This presentation will be focused on the compact antenna test range system, including the design, quiet zone results and diagnostic tools. We would like to share some recent quiet-zone measurement results, especially for base station antenna application at low frequencies. Analysis of time and direction of arrival (TDOA) of field probe data was used as diagnostic tool to locating various stray signals incident in quiet-zone. By this method, the relative time and angular location of stray source can be determined.
