Test Methodology for Adaptive Antenna Systems.
Abstract
Conventional antenna evaluations to determine gain, pattern, polarization, and terminal impedance characteristics are conducted on a component level. Adaptive antenna evaluations extend conventional antenna evaluations to system-level tests that quantify the performance of a receiving antenna system in both interference-free and interference environments. Test procedures for conventional antenna evaluations are well established. Test procedures for adaptive antennas expand the scope of antenna testing, tend to be system specific, and represent particular scenarios for interference. Adaptive antenna evaluations require additional instrumentation having more general spectral capabilities than conventional antenna test equipment, as well as an rf measurement facility capable of simultaneously generating both desired and interference signal components arriving from differing directions. The expansion of antenna testing for adaptive antenna designs is reviewed.
