Antenna measurement

资料介绍
Antenna_MeasurementsBasic Methods in Antenna Measurements The basic concepts in antenna measurements are presented in this module. First, a brief description of antenna ranges and anechoic chambers is given. Second, the basic methods for measuring the far-field patterns, the gain, the directivity, the radiation efficiency, the impedance and the polarization are discussed.

1. Introduction
1.1. Most of the methodology for measuring the characteristics of antennas was developed before and during World War II. The basic methods for the measurement of antenna far field patterns, antenna polarization, antenna input impedance, gain and directivity were developed during the above period in conjunction with the design of novel radiating structures, which were needed in the rapidly expanding telecommunication and rada
