Design Considerations for Wireless Antenna Testing
Author:Donald G. Bodnar, Ph.D.
This paper describes a new measurement system for testing antennas used in wireless communication system. A two-axis dielectric AUT positioner is used to reduce pattern perturbations, a vector network analyzer is employed for the receiver, and a broadband source antenna is utilized. RF test system design considerations are discussed including chamber design size. Software requirements that are unique to the needs of the wireless communication community are covered. The system is capable of making both far-field and spherical near-field measurements. A wide variety of antenna types can be tested using this system including handsets, laptop computers, and base station antennas.
