Abstract :
A low cost anechoic measuring system has been designed, constructed and evaluated. It consists of a small anechoic chamber, designed specifically for measurements of high performance feed horns within the range 18-30 GHz, and a simple antenna positioner. The chamber features hinged sides to ease relocation and improve access and is characterised by a simple aid low cost design in addition to a reflectivity level better than -52 dB. The antenna positioner is under the control of a PC which interfaces with a network analyser to achieve a fully automated magnitude and phase pattern measuring system.
