900 MHz miniature antenna for uses requiring conformity to highly bended surfaces

Authors propose own original geometry of a zero thickness antenna element. It occupies barely 10 cm² area and operates at 950 MHz frequency band with demonstrated potential to provide another, 1600-2700 MHz band defined with 10 dB return loss limits. Main advantage of the element is maintenance of a good impedance match when the element circuit conforms to bended surfaces likely to occur in real life. Furthermore, the good impedance match remains under a presence of nearby lossy objects and a PCB substrate. Finally, the proposed element is demonstrated as a wearable antenna.
