Abstract: A radio-frequency identification (RFID) antenna, per an implementation, includes a substrate, a metalized pattern, one or more slots, a ground plane, a shorting strip, and one or more feed lines. The metalized pattern has microstrip segments and a lateral microstrip. The slot(s) is situated between the microstrip segments. The ground plane extends from the substrate via the shorting strip. The feed line(s) resides on a surface of the substrate. In a slot mode of use of the RFID antenna, an electromagnetic field radiates from the slot. In a patch mode of use of the RFID antenna, an electromagnetic field radiates adjacent ends of the metalized pattern.

Abstract: A method for decontaminating a tube includes positioning an antenna at least partially within the tube. The tube is positioned at least partially within a living body. The method also includes decontaminating the tube by causing the antenna to emit electromagnetic waves having a frequency from about 10 GHz to about 100 GHz for a time duration that is less than or equal to 60 seconds. The electromagnetic waves cause a temperature of the living body proximate to the tube to increase from about 0.1° C. to about 3° C. so as to not substantially damage the living body.

Abstract: A system for decontaminating a tube includes a signal generator configured to generate a signal. The system also includes an antenna configured to receive the signal from the signal generator. The antenna is configured to be inserted at least partially into a tube that is positioned at least partially within a body. In response to receiving the signal from the signal generator, the antenna emits electromagnetic waves that at least partially decontaminate the tube. The electromagnetic waves have a frequency from about 10 GHz to about 100 GHz. The electromagnetic waves cause a temperature of the body proximate to the tube to increase less than about 3° C. over a time duration that is up to 40 seconds.
