Prototype High Angular Resolution LEKIDs for NIKA2

The current resolution of the NIKA2 260 GHz arrays is limited by the \(1.6\times 1.5~\mathrm{mm}^2\) inductor size on the individual pixels. In view of future updates of the instrument, we have developed a prototype array with smaller pixels that is experimentally compared to the current pixel design. In laboratory, we find an increase of the angular resolution of 8%, promising an on-sky FWHM resolution of \(10.2''\) using this new pixel design.
