A medical device as described herein includes a communication module to process radio frequency signals associated with operation of the medical device, an antenna associated with the communication module, and a microstrip transmission component coupled between the communication module and the antenna. The transmission component includes a dielectric substrate, an electrically conductive signal trace formed overlying the upper major surface of the substrate, an electrically conductive ground plane formed overlying the lower major surface of the substrate, and a complementary split ring resonator arrangement integrally formed in the ground plane, and having a layout and dimensions tuned to cause the resonator arrangement to resonate at one or more harmonic frequencies of the nominal transmission frequency of the radio frequency signals.

Wireless medical device with a complementary split ring resonator arrangement for suppression of electromagnetic interference

An electronic device may include a first substrate, an electrically conductive feed line on the first substrate, an insulating layer on the first substrate and the electrically conductive feed line, a second substrate on the insulating layer, and an antenna on the second substrate and having nanofilm layers stacked on the second substrate. The antenna is coupled to the feed line through an aperture.
