Abstract In this article, the receiving properties of a fractal antenna coupled to a film of single‐walled carbon nanotubes used as a bolometer are numerically and experimentally investigated in the megahertz frequency region. The numerical results show resonant frequencies at 420 and 1710 MHz, close to the 500 and 1600 MHz resonant frequencies obtained experimentally, the responsivity of the devices was calculated at 0.178 V/W at 610 MHz for an i bias of 0.3 μA. © 2012 Wiley Periodicals, Inc.
