IPC: G01R29/10
Filed: 1987-03-04
Abstract: PURPOSE:To reduce a difference between receiving levels and measure an antenna efficiency with a high accuracy by arranging metallic wave scattering bodies around a transmitting antenna to be measured or a reference transmitting antenna and arranging a wave shielding curtain between transmitting and receiving antennas. CONSTITUTION:A transmitting antenna 12 to be measured or used as a reference is connected to an oscillator 13 for electrifying the transmitting antenna 12. Around the transmitting antenna 12 including the portion above it, wave scattering bodies 11 are arranged. The wave scattering bodies 11 include a plurality of metal plates with arbitrary areas and configurations and are hung from, for example, a ceiling. Further, a wave shielding curtain 20 is arranged between the transmitting antenna 12 and a receiving antenna 14.
