An alternative method to compute the free-space antenna factor using time-domain transformation and deconvolution filter for pulse compression is proposed. The deconvolution filter helps in compressing the time-domain pulse to distinguish the direct

The ANSI C63.5-2006 standard stipulates a symmetry test to check the antenna balance. The s21 response between two similar antennas, placed at 1m height above the ground plane, is first recorded. The antenna under test is rotated 180° and the respon
