Obviousness

The provided patent text for US11349200 and its accompanying metadata do not explicitly list specific prior art references (e.g., other patent numbers, publications, or disclosures) that can be combined to perform an obviousness analysis under 35 U.S.C. § 103. The "Prior art keywords" section only provides general terms such as "antenna," "rectangle," "contour," "mfwd," and "wireless device," rather than citable documents.

While the patent's background section discusses various challenges and characteristics of existing antenna designs for multifunction wireless devices (MFWDs)—such as the size and bandwidth limitations of small antennas, the difficulties in achieving multi-band operation, and the poor gain and narrow bandwidths of patch antennas—it does not identify these as specific prior art references that can be cited and combined according to the user's instructions. Therefore, without specific prior art references, a detailed obviousness analysis identifying combinations of such references and motivations for their combination cannot be conducted.
