In this article, the input impedance (i.e., feed point impedance) of a 600‐GHz membrane‐based twin slot antenna for superconducting hot‐electron‐bolometer (HEB) mixers is investigated through numerical simulation and scale model measurement. The twin‐slot antenna, with an RF choker filter included, was designed with the aid of Microwave Studio CST. A 200‐times scale model of the designed twin slot antenna was fabricated to validate the simulated results. For the scale model measurement, de‐embedding measurement technique was adopted to extract the input impedance of the twin slot antenna. The measured results are found in good agreement with the simulation. © 2009 Wiley Periodicals, Inc.
