Electrical tape and copper wire. wrap the wire a few times around the point, tape it up. hang the slack somewhere over your desk or case

you could take a trip to the shops and buy an arial

get the coax cable  from the tv.
and try to see if it fits,
or itll do with the clip if it doesnt

You can use these makeshift antennas, but they will not give you very good performance, especially for digital date, Mbps of bandwidth, at high frequencies.

Any commercially produced antenna you but would have been engineered for the specific bands used by WiFi,  properly polarised and such. One of these will give you much better performance than a coat hanger could (even if they are good for FM).
