A single-antenna method for traceable antenna gain measurement

A simple method is introduced to measure the gain factor of a single prefer ably directional linearily polarized antenna in whatever distance. It requi res only equipment for usual insertion loss measurement and the antenna its elf in front of a totally reflecting surface simulating a second identical antenna as the image of the antenna to be calibrated. This speeds up such m easurements considerably and, therefore, is very cost efficient. Its result s can easily be made traceable to national standards.
