An access point's wireless card generates a very weak signal, so to minimize signal loss I wanted the antenna cable to be as short as possible.

The antenna membrane hangs in a hollow bony chamber, allowing for quick heat loss and maximizing the detected temperature differences between warm-blooded animals and everything else.

A new broadband slot antenna with a fan-shaped microstrip feed is presented, and the return loss curve and radiation patterns of the antenna is simulated in this paper.
