Abstract :
Methods of field-strength measurement are reviewed briefly and the design of field meters conforming closely to the conditions imposed by antenna theory is considered Two instruments approaching ideal theoretical conditions and suitable for reference standards are described. The first of these contains an adjustable matching network. The second utilizes very fine wires on a styrofoam support.
