About this 3D model

This is a slotted waveguide antenna for the tp-link WR703N wifi travel router. It fits over the box, so no modifications to the router are needed. It changes the radiation pattern to a pie-segment shape: horizontally it is about 120degrees wide, vertically it is much narrower. The dimensions are limited by the lasercutter I used, an antenna with more slots would give a better gain. I have not tested this antenna yet...
