Wearable Stretchable Antenna with Constant Frequency, Far-Field Communication Capability

Antennas are key components of all forms of modern communications – from Bluetooth to satellite phones. Antennas are basically metallic structures that radiate electromagnetic waves which can be used to carry information. While flexible patch antennas can be used to make flexible communication circuits possible, the fabrication of stretchable communication circuits is a challenge. Stretchable circuits can be of use in applications such as wearable electronics for continuous body vitals monitoring for advanced diagnostics. Such skin mountable electronics circuits require the ability to absorb some amount of strain (because of the stretchability of the skin). This is where a stretchable antenna capable of uninterrupted communication during stretching can be useful.
