Antenna Factor recognizes that our antennas areoften used in compact applications with less than ideal groundplanes. In some cases, the reference jig is smaller than optimum,particularly with lower-frequency antennas. This is, in part, tomore accurately reflect the performance of the antenna in typicalreal-world applications.ABOUT THIS TEST FIXTURE
