Enhancement of antenna-coupled microbolometers response by impedance matching

Metallic structures were evaluated to determine the one best matches impedance between lithographic antennas and microbolometers. The best was a 0.28λ transmission line section between the antenna and the microbolometer, 12%25 longer than what RF theory sets, whose behaviour was compared with other structures. The response was 360%25 higher. © 2015 Universidad Nacional Autónoma de México, Centro de Ciencias Aplicadas y Desarrollo Tecnológico.
