Development of a cost effective antenna radiation pattern measurement setup
Nov 16, 2016
This paper presents an insight on the recently developed antenna pattern measurement system at COMSATS Institute of Information Technology (CIIT), Islamabad, Pakistan. Microwave Components and Devices (MCAD) research group at CIIT has been involved in antenna focused research activities but unavailability of anechoic chamber to measure radiation patterns has remained a huge handicap. In this regard efforts have been made to indigenously develop a radiation pattern measurement system. The system can measure radiation patterns from 600 MHz up to 26 GHz. The reflections from surroundings are suppressed by filtering the delayed signals in time domain. The system is automated through a Labview program which also provides users with the control and flexibility on various parameters. The system can provide gain at four frequency points simultaneously along with phase information.
