Broadband Characterization of Millimeter-Wave Log-Periodic Antennas by Photoconductive Sampling

Results of photoconductive sampling measurements used to characterize millimeter-wave log-periodic antennas with continuous, simultaneous frequency coverage from 10 to 300 GHz are presented. Polarization properties are investigated employing wire-grid polarizers. This study reveals new information on structure resonances and antenna polarization. © 1994 IEEE
