This web site provides Global Navigation Satellite System (GNSS) antenna calibrations for specific antenna types (antenna code + radome code). These calibrations are used by NGS for processing GNSS data in all its products and services. NGS offers complete, downloadable files of absolute antenna calibrations in both ANTEX and ANTINFO formats.

CISPR 16-1-6, the newcomer. The standard provides procedures and information on the calibration of antennas for determining antenna factors (AF) that are applicable to antennas intended for use in radiated emission measurements in accordance with CISPR 16-2-3. The frequency range addressed is 9 kHz to. 18 GHz.
En las antenas de EMC se calibra el factor de antena, (AF, Antenna Factor ), FA, que es una magnitud de depende de la frecuencia y de la geometría en que se mide, esto es la altura de la antena,ladistanciadepruebaylapolarizaciónde la antena.
To illustrate the value of antenna calibration, this white paper covers four core topics: the two main types of antennas, the essential measures of antenna performance, ways to ensure accurate calibration, and the attributes of a qualified calibration lab.
LECTURE 8: Basic Methods in Antenna Measurements. (Antenna ranges and anechoic chambers. Measuring far-field patterns, gain, directivity, radiation efficiency, input impedance and polarization.) 1. Introduction*. Many of the basic methods for measuring antenna characteristics were developed before and during World War II.
This work describes the development of antenna-calibration instrumentation. The purpose of the antenna calibration instrumentation is to provide reliable tools for the assessment, calibration, and performance improvement of the large number of antenna systems in the DSN. Utilizing the
